HX711 features dual-channel 24 Bit Precision A/D Weight Pressure Sensor Load Cell Amplifier which is available in a small breakout board. The board has pinouts for the microcontroller and the Load cell in two different directions for the ease of interfacing. It can be interfaced with any microcontroller using Data and Clock pins.
This module supports input voltage from 2.7V to 5V, making it ideal for the 3.3V and 5V microcontroller operations. A Resistive Load cell with two differential inputs can be used with this module and could achieve high accuracy in low and high weight measurements.
This low cost, analog front load cell amplifier is the perfect choice for Balance and load cell interfacing. The current consumption of this amplifier is also low with less than 1uA in power down state and 1.5mA only in normal operation or active state.
