It interfaces directly with a \u003cstrong\u003eWheatstone bridge load cell\u003c\/strong\u003e and outputs digital weight data to a microcontroller via a simple 2-wire serial interface (CLK + DOUT). With 24-bit resolution and a built-in programmable gain amplifier (PGA), it enables accurate weight measurement from milligrams to hundreds of kilograms depending on the load cell used.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eIC\u003c\/td\u003e\n\u003ctd\u003eHX711\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eADC Resolution\u003c\/td\u003e\n\u003ctd\u003e24-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eInput Channels\u003c\/td\u003e\n\u003ctd\u003eChannel A (PGA 128\/64) + Channel B (PGA 32)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eOutput Data Rate\u003c\/td\u003e\n\u003ctd\u003e10Hz or 80Hz (selectable via RATE pin)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e2.7V – 5.5V (3.3V and 5V compatible)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003e2-wire serial (CLK + DOUT), compatible with any GPIO\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eInput Sensitivity\u003c\/td\u003e\n\u003ctd\u003e±40mV full-scale differential input\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCompatible Load Cells\u003c\/td\u003e\n\u003ctd\u003eAny 4-wire Wheatstone bridge load cell (1kg, 5kg, 10kg, 50kg, etc.)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eCN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhy Use the HX711?\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e24-bit resolution\u003c\/strong\u003e — Provides 16 million counts of resolution for highly accurate weight readings even with low-capacity load cells\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt-in PGA\u003c\/strong\u003e — Programmable gain of 32\/64\/128 amplifies the tiny millivolt signal from the load cell without external op-amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSimple 2-wire interface\u003c\/strong\u003e — No I2C address conflicts, no SPI bus sharing; works with any two GPIO pins on Arduino, ESP32, or Raspberry Pi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow noise\u003c\/strong\u003e — Differential input rejects common-mode noise from power supply and EMI, critical for stable weight readings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWide library support\u003c\/strong\u003e — Arduino HX711 library (bogde\/HX711) provides tare, calibration, and averaging functions out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTypical Applications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eDIY kitchen and postal scales\u003c\/li\u003e\n  \u003cli\u003eArduino and ESP32 weight measurement projects\u003c\/li\u003e\n  \u003cli\u003eIndustrial force and torque measurement\u003c\/li\u003e\n  \u003cli\u003eFilament spool weight monitoring for 3D printers\u003c\/li\u003e\n  \u003cli\u003eSmart plant pot soil moisture estimation via weight change\u003c\/li\u003e\n  \u003cli\u003eLuggage and parcel weight checking stations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eQ: Does this module include a load cell?\u003c\/h3\u003e\n\u003cp\u003eNo. This module is the HX711 ADC amplifier board only.
