Key Features:
- Dimensions: 33mm x 21mm
- Hx711 Chip: The core of the module is the Hx711 chip, a 24-bit precision analog-to-digital converter (ADC) designed specifically for load cell applications.
- Load Cell Interface: The module connects to strain gauge load cells, which convert physical pressure into electrical signals. It measures very small voltage changes from the load cell.
- High Precision: The Hx711 offers a high-resolution reading with a precision of up to 24 bits, ensuring accurate weight measurement.
- Low Power Consumption: Ideal for battery-operated devices.
- Selectable Gain: The module allows selectable gains of 32, 64, or 128 to adapt to different load cell outputs.
- Analog Input: It amplifies low-amplitude analog signals from the load cell and converts them into digital form for microcontroller interfaces like Arduino or Raspberry Pi.
- Simple Wiring: It uses only 2 data lines (clock and data) to communicate with the microcontroller, simplifying the design.
- Applications: Commonly used in digital weighing scales, industrial process control, and precision force sensors.
Pin Description:
- VCC: Power supply (typically 2.6V to 5.5V)
- GND: Ground
- DT (Data): Data output from the Hx711 to the microcontroller
- SCK (Clock): Clock signal for synchronous data transfer
This sensor module is widely used in electronic scales and pressure measurement systems due to its high accuracy and ease of use.
