HX711 Weight / Load Cell 2 Channel Pressure Sensor Amplifier Module for Arduino / DIY / PIC
Our HX711 Load Cell Amplifier is a low-cost A/D converter module incorporating a very high precision 24 bit ADC and differential high gain inputs that allow you to easily read load cells, bridge sensors, pressure, strain and weight sensors to measure weight. By connecting the amplifier to a microcontroller, you can read the changes in the resistance of the load cell and with some calibration, you’ll be able to get very accurate weight measurements. This can be used to create your own weight scale, process control, or simple presence detection. Based on Avia Semiconductor’s patented technology, HX711 is a precision 24-bit analog-to-digital converter (ADC) designed for weight scales and industrial control applications to interface directly with a bridge sensor. The input multiplexer selects either Channel A or B differential input to the low-noise programmable gain amplifier (PGA). Channel A can be programmed with a gain of 128 or 64, corresponding to a full-scale differential input volt
