Default Title

TMP36GT9Z Analog Temperature Sensor — TO-92, -40°C to +125°C, 10mV/°C

The TMP36GT9Z is a precision analog temperature sensor from Analog Devices that outputs a voltage linearly proportional to temperature at 10mV/°C. With a measurement range of -40°C to +125°C, no external calibration required, and a simple 3-pin TO-92 package, it is one of the easiest temperature sensors to use with Arduino and any ADC-equipped microcontroller.

Key Specifications

Parameter Value
Part Number TMP36GT9Z
Package TO-92 (through-hole)
Supply Voltage 2.7V – 5.5V
Output Analog voltage (10mV/°C)
Temperature Range -40°C to +125°C
Accuracy ±2°C (typical at 25°C)
Output at 25°C 750mV
Quiescent Current 50μA (typical)
No Calibration Required Yes

Arduino Reading Formula

float voltage = analogRead(A0) * (5.0 / 1023.0);
float tempC = (voltage - 0.5) * 100.0;
  • At 25°C: output = 750mV → (0.75 - 0.5) × 100 = 25°C ✔
  • At 0°C: output = 500mV
  • At -40°C: output = 100mV

Why Choose TMP36?

  • No calibration needed — factory-calibrated, plug-and-read
  • Simple analog output — read with any ADC pin, no I²C/SPI library required
  • 2.7–5.5V supply — compatible with 3.3V and 5V Arduino boards
  • 50μA quiescent current — suitable for battery-powered sensor nodes
  • TO-92 package — breadboard and through-hole PCB compatible

Typical Applications

  • Arduino ambient temperature measurement
  • Data logger temperature sensing
  • Thermostat and temperature controller input
  • PCB and enclosure temperature monitoring
  • Weather station temperature sensor
  • Battery temperature monitoring
