Couldn't load pickup availability
The 7Semi HX711 Load Cell Amplifier Module is a high-precision 24-bit analog-to-digital converter (ADC) tailored for weight measurement tasks such as industrial scales and process control applications.
It features two selectable differential input channels and a built-in low-noise programmable gain amplifier (PGA) with gain options of 32, 64, and 128, ensuring accurate and flexible signal amplification.
Thanks to its simple two-wire serial interface, the module is easy to integrate with microcontrollers like Arduino, Raspberry Pi, and others.
Operating within a supply voltage range of 2.6V to 5.5V, it offers selectable output data rates of 10 samples per second (SPS) or 80 SPS, allowing users to balance between speed and accuracy according to their project needs.
The 7Semi HX711 load cell sensor is an ideal choice for applications requiring precise, stable, and reliable weight sensing.
