The HX711 Weighing Pressure Sensor Module is a 24-bit analog-to-digital converter (ADC) widely used in digital scales and industrial weight measurement applications. It features two selectable differential input channels and an on-chip low-noise programmable gain amplifier (PGA) with gain options of 32, 64, and 128. With built-in power supply regulation, oscillator, and power-on reset, the module ensures stable operation without requiring external components. It supports simple digital control via a serial interface and offers simultaneous 50Hz and 60Hz supply rejection for noise-free readings. Operating within a voltage range of 2.6V–5.5V, it consumes less than 1.5mA during normal operation and under 1µA in power-down mode. Compact in size (34 x 21 x 3mm), this module is ideal for digital scales, weighing systems, and other precision measurement projects.
