HX711 Module Weighing Sensor Module in Pakistan

HX711 module is a Load Cell Amplifier breakout board for the HX711 IC that allows you to easily read load cells to measure weight.

HX711 Module specially designed for the high precision electronic scale design, with two analog input channel, the internal integration of 128 times the programmable gain amplifier.

The HX711 Weighing Sensor Module uses a two-wire interface (Clock and Data) for communication. Any microcontroller’s GPIO pins should work and numerous libraries have been written making it easy to read data from the HX711.

Load cells use a four-wire Wheatstone bridge to connect to the HX711 Module. These are commonly colour RED, BLK, WHT, GRN, and YLW.

HX711 Module is an electronic scale sensor, whose working principle is to convert the measured changes in resistance value changes, through the conversion circuit into electrical output. The module communicates with the host computer through TTL 232.

Advantages

Simple structure, easy to use, stable and reliable performance, high sensitivity and measurement speed and so on.

HX711 Sensor Application

Widely used in aerospace, mechanical, electrical, chemical, construction, medicine and many other fields, used to measure force, pressure, displacement, strain, torque, acceleration.
