The module uses a 24-bit high precision A/D conversion chip HX711.
The input circuit can be configured to provide a bridge.
The electric bridge voltage sensor model (such as pressure, weight) is an ideal sampling module with high precision and low cost. HX711 Module Weighing Pressure Sensor 24 Bits features:
- Two selectable differential input channels
- Active low noise PGA with selectable gain of 32, 64 and 128
- Power supply regulator for load cell and ADC analog power supply
- Oscillator on chip that does not require external component with optional external glass
- Power-on-reset on the chip
- Simple serial control and serial interface: controls driven by pins, programming is not required
- Output data rate 10SPS or 80SPS selectable
