Description:
The HX711 Load Cell Amplifier Sensor Digital Interface Module is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications. It interfaces directly with a bridge sensor, such as a load cell, to provide accurate weight measurements. The module features a low-noise programmable gain amplifier (PGA) with selectable gains of 32, 64, and 128, allowing it to accommodate various sensor outputs. Its simple digital control and serial interface facilitate easy integration with microcontroller platforms like Arduino and Raspberry Pi.
Operating over a wide supply voltage range of 2.6V to 5.5V, the HX711 module offers two selectable differential input channels, enabling the connection of multiple load cells. It provides selectable output data rates of 10 samples per second (SPS) or 80 SPS, ensuring flexibility in data acquisition speed. The module’s on-chip power supply regulator eliminates the need for an external supply regulator, simplifying the design of weighing systems. Its compact design and high precision make it an ideal choice for applications requiring accurate weight measurement and digital interfacing.
