HX711 ( HX 711 ) Load Cell Amplifier Module uses 24 high-precision ADC converter chip hx711, is designed for high-precision electronic scale and design, with two analog input channels. 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 voltage of ±20mV or ±40mV respectively, when a 5V supply is connected to AVDD analogue power supply pin. Channel B has a fixed gain of 32. .The input circuit can be configured to provide a bridge voltage electrical bridge (such as pressure, weight) sensor model is an ideal high-precision, low-cost sampling front-end module.There is no programming needed for the internal registers. All controls to the HX711 are through the pins.
