HALJIA HX711 High-precision Electronic Weighing Sensor 24-bit A/D AD Dual-channel Conveter Module Compatible with ARM AVR Arduino Raspberry Pi

HX711 is a designed for high-precision electronic scales designed for 24-bit A / D converter chip. Compared with the same type of other chip that integrates the peripheral circuits including power supply, on-chip clock oscillator with other types of chips needed, high integration, fast response, strong anti-interference advantages. Reducing the overall cost of the electronic scale, improving the overall performance and reliability. The chip with the rear end of the MCU chip interfaces and programming is very simple, all control signals from the pin driver without internal chip registers. Input selector switch can select any channel A or channel B, and its low-noise programmable internal amplifier is connected. A channel programmable gain of 128 or 64, corresponding to the full amount of the differential input signal amplitude was ¡À 20mV or ¡À 40mV. Channel B, compared with a fixed gain of 32 for the parameter detection system. Two selectable differential inputsRene-chip programmable
