JOY-IT DEBO HX711-20 24-Bit ADC Module with 20 kg Load Cell for Weight Measurement SEN-HX711-20

The JOY-IT DEBO HX711-20 is a precision 24-bit analog-to-digital converter module paired with a 20 kg strain gauge load cell, enabling accurate weight measurement for electronic scales and industrial control applications. Its integrated programmable gain amplifier ensures reliable signal conditioning for microcontrollers like Arduino, Raspberry Pi, and ESP32.

Advantages

The HX711 chip features two differential input channels, selectable gain (32, 64, 128), and a low-noise on-chip amplifier, delivering stable readings even with small load changes. The module operates from 2.6V to 5.5V DC and consumes less than 1.5 mA, making it suitable for battery-powered projects.
