is directly readable in degrees Celsius using an analog port on a uC.  Accuracy is typically within 0.5°C.\u003c\/p\u003e\n\u003cp\u003eSince the voltage output range of the sensor is limited to 1.5V, if a greater resolution is desired, the analog reference voltage on the uC can be changed from the default 5V to something closer to 1.5V which will decrease the voltage step size on the analog readings.\u003c\/p\u003e\n\u003cp\u003eHook-up is very simple.  Connect GND pin to ground, Vs pin to 5V (or anything between 4 – 20V) and Vout pin to an analog pin on the uC.  The device can be left open air for measuring air temps or it can be glued or cemented to an object that you want to measure the temperature of such as a heat sink.\u003c\/p\u003e\n\u003cp\u003eWhen using the LM35 with a single supply voltage, the temperature measurement range is limited to 2°C to 150°C which is adequate for most applications.  If the negative range is required, see the datasheet for specifics.\u003c\/p\u003e\n\u003cp\u003eAn alternative for temperature measurement is to use a digital temperature sensor like the DS18B20 which comes in the same package.  Digital temp sensors tend to have better noise immunity which is useful when the sensor will be placed some distance away or is in an electrically noisy environment, but they do require a software library to implement the communication protocol.  Libraries are readily available for most common microcontrollers such as the Arduino and are very straightforward to use.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eOUR

self-contained switching module that energizes \/ de-energizes a relay based on the temperature.   Just add 5V power and hook up the load you want to control then adjust the potentiometer to set the temperature at which you want the relay to switch between ON \/ OFF.\u003c\/p\u003e\n\u003cp\u003eThis type of module can be used for applications such as to automatically turn on an exhaust fan when the temperature gets above a preset level as might be the case in a green house or aquarium room or it could be used to energize a heating device when the temperature drops below a preset level.\u003c\/p\u003e\n\u003ch3\u003eTheory of Operation\u003c\/h3\u003e\n\u003cp\u003eThe temperature sensor on the module is a standard thermistor.\u003c\/p\u003e\n\u003cp\u003eThe temperature

goes over the trip-point value, an LM393 voltage comparator IC energizes the relay and it switches ON.  A green LED is illuminated when the relay is energized.\u003c\/p\u003e\n\u003cp\u003eWhen the temperature drops below the preset value, the relay switches back OFF.\u003c\/p\u003e\n\u003cp\u003eThe relay has both NO (Normally Open) and NC (Normally Closed) contacts so the module can either be used to energize a load when temperature goes up past the trip-point value or when it goes down past that level.\u003c\/p\u003e\n\u003cp\u003eA flyback diode is included on the module in parallel to the relay coil to safely shunt current when the relay coil is de-energized.\u003c\/p\u003e\n\u003ch3\u003eModule Connections\u003c\/h3\u003e\n\u003ch4\u003ePOWER\u003c\/h4\u003e\n\u003cp\u003eThe

for a number of applications and allow you to control devices based on temperature without the need to have a uC involved.  Just hook up 5V power and your load and you are all set.\u003c\/p\u003e\n\u003cp\u003eWe do find the DC rating of the relay to be too aggressive. With DC voltages above about 15V, the contacts can become a little sticky. We recommend using it to switch DC voltages of no more than 15V.\u003c\/p\u003e\n\u003cp\u003eWith AC, the relays performed very well in our testing.  To test the upper limit we used it to switch a 1500W heater that draws about 12.5A and the relay handled it without any problems though you should not exceed 10A in normal use.\u003c\/p\u003e\n\u003cp\u003eTo test the device, connect it to power and adjust the pot so that the green LED just goes out.  Warming the thermistor should cause the green LED to come on and an audible click heard from the relay as it switches.\u003c\/p\u003e\n\u003cp\u003eTo adjust the pot for the final application will take a little trial and error since the module uses a relative adjustment rather than being able to set it to a specific temperature level.  There is also quite a bit of hysteresis in the switching.  If you are trying to maintain a particular temperature with a level of precision, check out our W1209 and W1219 temperature controller modules below which may offer better value for your application.\u003c\/p\u003e\n\u003cp\u003eIf the module has long leads on the thermistor, ensure the leads stay separated and

outputs.\u003c\/p\u003e\n\u003cp\u003eThermistors are essentially resistors whose resistance value changes with changes in temperature.  NTC stands for ‘Negative Temperature Coefficient which means that the sensor resistance will decrease as temperature increases.\u003c\/p\u003e\n\u003cp\u003eThe thermistor is in series with an 10K resistor which creates a voltage divider.  As the thermistor warms up, the resistance lowers and the analog output either increases towards Vcc or decreases toward ground depending on the module construction.\u003c\/p\u003e\n\u003cp\u003eThere is a red LED1

voltage output from the thermistor.  This is normally input into an analog port on an MCU where it can be read and the temperature can be calculated.\u003c\/p\u003e\n\u003cp\u003eThe digital (\u003cstrong\u003eD0\u003c\/strong\u003e) output is normally LOW and goes HIGH when a temperature threshold has been reached.  When the output goes HIGH, LED2 lights.  The set-point for the temperature threshold can be adjusted using the potentiometer on the module.  Turning the adjustment CCW increases the temperature set-point.  This output is normally connected to a digital input on an MCU or could directly control a relay or similar device once the temperature threshold has been reached.\u003c\/p\u003e\n\u003ch3\u003eModule Connections\u003c\/h3\u003e\n\u003cp\u003eThere is a

basic humidity and temperature measurement.  Once up and running with a microcontroller, it is easy to test basic functionality of the module by breathing on the sensor.  That will increase both humidity and temperature temporarily.\u003c\/p\u003e\n\u003cp\u003eThe DHT11 has a narrower measurement range and lower accuracy compared to the similar DHT22 sensor which is why it costs less. If you are looking for best accuracy, you may want to check out our DHT22 module below.\u003c\/p\u003e\n\u003cp\u003eThe sensor can not be polled faster than once every second, otherwise data errors may occur.  If you get occasional bad readings (such as -999.00) try increasing the delay between reads.  Our sample program below uses a 2 second delay just to be safe.\u003c\/p\u003e\n\u003cp\u003eOnce the DHT library is installed, using the device is fairly simple as shown in the code below.\u003c\/p\u003e\n\u003ch3\u003eDHT11 Humidity \/ Temperature Sensor

accuracy compared to the similar DHT11 sensor which is why it costs more.  If you are looking for a less expensive option, check out our DHT11 Module below.\u003c\/p\u003e\n\u003cp\u003eThese sensors are often spec’d to read temps of up to 125C.  While the circuit will indeed measure temps that high, the plastic housing will start to deform, therefore I recommend not using it at temps higher than 80C which is higher than most applications will require anyway.\u003c\/p\u003e\n\u003cp\u003eThe sensor can not be polled faster than once every 2 seconds, otherwise data errors may occur.  If you get occasional bad readings (such as -999.00) try increasing the delay between reads.  Our sample program below uses a 3 second delay just to be safe.\u003c\/p\u003e\n\u003cp\u003eOnce the DHT library is

reading has a 14-bit resolution by default.\u003c\/p\u003e\n\u003cp\u003eThe sensor has a small window for air to contact the sensor.  Keep contaminates away from the window as that can affect the accuracy of the humidity reading.  The window must remain open to the air, but it can be protected from dust and similar contaminates with a PTFE membrane, gauze or other material that still allows air to flow through or by positioning it in an enclosure where air passes through but is protected from excess dust or moisture.\u003c\/p\u003e\n\u003cp\u003eIf soldering to the board, it is safest to

for basic humidity and temperature measurement.  Once up and running with a microcontroller, it is easy to test the module by breathing on the sensor.  That will increase both humidity and temperature temporarily.\u003c\/p\u003e\n\u003cp\u003eThe sensor can not be polled faster than once per second, otherwise data errors may occur.  If you get occasional bad readings (such as -999.00) try increasing the delay between reads.\u003c\/p\u003e\n\u003cp\u003eThere are other sensors in this line such as the DHT22.  In general, as the number gets higher, the measurement range or accuracy of the device increases (as does the price).  The DHT11 is a good sensor to get started with, but if you are looking for best performance, check out our DHT22 down below.  This is the lowest cost humidity sensor module that we sell.  We also have a similar DHT11 module that has a little nicer construction and comes with hookup wires that is available below as well.\u003c\/p\u003e\n\u003cp\u003eOnce the DHT library is installed, using the device is fairly simple as shown in the code snippet below.  In this case we are using pin 7, but any digital pin can be

read and the temperature calculated.\u003c\/p\u003e\n\u003cp\u003eThermistors are essentially resistors whose resistance value changes with changes in temperature.  NTC stands for ‘Negative

voltage divider.  As the thermistor warms up, the resistance lowers and the analog output increases towards Vcc.\u003c\/p\u003e\n\u003cp\u003eThe sensor is capable of reading temperature in the range

measurement.  Once up and running with a uC, it is easy to test the module by using the fingers to warm the sensor and monitor the output.\u003c\/p\u003e\n\u003cp\u003eUsing the device requires some math to convert from the voltage output to the temperature.  In our own test code, we use the Beta method for temperature calculation, but there are several different formulas that can be used.  The nice thing about the Beta method is that you can measure your component values and enter them into the fields if your sensor is constructed a little different.\u003c\/p\u003e\n\u003cp\u003eThe most difficult part is calculating the Beta value which is in the datasheet if you are using a fully spec’d part.  If the part is unknown, as is the case with most of these types of modules, you can calculate it.  This link is for a handy\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/www.ametherm.com\/blog\/thermistors\/thermistor-beta-calculations\" rel=\"noopener noreferrer\"

It needs to start after running the set delay time.\u003cbr\u003eHeating mode: For the first time, if the current temperature is less than the set value, the heater will not start heating immediately, and it needs to run the set delay time to start.\u003cbr\u003eWhen the downtime between two adjacent starts of the chiller or heater is greater than the set value of the delayed start time, the chiller starts immediately.\u003cbr\u003eWhen the stop interval between two adjacent starts of the cooler or heater is less than the set value of the delayed start time, the equipment can be started only after the refrigeration delay start time is completed. The delay time is calculated from the moment of shutdown.\u003cbr\u003eFor example, in the refrigeration state, the delay is set to 5 minutes, and the chiller starts the delay after the machine is turned on. When the chiller starts up after 5 minutes, the chiller stops when the required temperature is reached, and the timing starts at this time. When the next chiller starts the timing, it will work immediately.\u003cbr\u003eIf delay start is set to 0, the delay function is disabled.\u003cbr\u003eHow to Save Settings\u003cbr\u003eTo save the set data, set P7 to ON when the power is on after setting the temperature. In this way, the last setting will be kept when the power is off.\u003cbr\u003e\u003cbr\u003eP8 factory data reset\u003cbr\u003eDue to some human reasons, the internal Settings of the thermostat are confused, and it takes a lot of time to set one item by one. At this time, this function can be used to restore factory Settings. The specific method is: in the shutdown state, press and hold the + and - buttons at the same time, and then start up, and all the above parameters will be restored to factory Settings.\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eFrequently Asked Questions (FAQ)\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eQ1: What Should I Do If I Receive A Damaged Item?\u003cbr\u003eA1: Please Contact Us Within 7 Days Of Receiving The Package, And We Will Provide A Solution.\u003cbr\u003eQ2: How Can I Contact Customer Service?\u003cbr\u003eA2: You Can Reach Us Through The AliExpress Messaging System, And Our Customer Service Team Will Respond During Business Days.\u003cbr\u003eQ3: How Important Is Feedback To You?\u003cbr\u003eA3: Your Feedback Is Crucial To Our Development, And We Sincerely Invite Satisfied Customers To Leave Positive Reviews.\u003c\/p\u003e\n\u003cdiv\u003e\u003cimg class=\"detail-desc-decorate-image\" src=\"https:\/\/ae01.alicdn.com\/kf\/Sfbc518e390764cb0bbf08f06f648df31g.jpg\" slate-data-type=\"image\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"detailmodule_text-image\"\u003e\n\u003cp style=\"font-family:OpenSans;font-size:20px;font-weight:900;line-height:28px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-title\"\u003eFeedback \u0026amp; Reviews\u003c\/p\u003e\n\u003cp style=\"font-family:OpenSans;font-size:14px;font-weight:300;line-height:20px;white-space:pre-wrap;color:rgb(0, 0, 0);margin-bottom:12px\" class=\"detail-desc-decorate-content\"\u003eWe Appreciate Your Timely Confirmation Upon Receiving Your Order.\u003cbr\u003eYour Feedback Is Vital To Us; If You Are Satisfied With Our Product And Service, Please Leave Positive Feedback.

signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability. Therefore, the product has the advantages of excellent quality, fast response, strong anti-interference ability and high cost performance. Each sensor is calibrated in a precision humidity calibration chamber. The calibration coefficients are stored in the OTP memory as a program, and these calibration coefficients are called internally during the processing of the detection signal. The sensor consists of a capacitive sensing element and an NTC temperature measuring element connected to a high performance 8-bit microcontroller. Communication with the microprocessor via a single bus requires only one line, 40 bits of data at a time, high first out. Small size, low power consumption, long communication distance, can be used in demanding applications.\u003c\/span\u003e\u003c\/span\u003e\n \u003c\/div\u003e\n \u003cdiv
