Description
The HX711 module is a digital load cell weight sensor that uses 24 high precision A/D converter chips. It has two selectable differential input channels and an on-chip active low noise PGA with selectable gain of 3264 and 128. It also has an on-chip power supply regulator for load-cell and ADC analog power supply, an on-chip oscillator requiring no external component with optional external crystal, and a simple digital control and serial interface. The HX711 can operate at a data rate of 10SPS or 80SPS and has a current consumption of normal operation < 1.5mA and power down < 1uA. It has a operating supply voltage range of 2.6 ~ 5.5V and a operating temperature range of -20 degree ~ +85 degree.
