HX711 Weighing Sensor 24-bit A/D Conversion Adapter Load Cell Amplifier Board

product description HX711 is designed for 24-bit A / D converter chip design of high-precision electronic scales. Integrated with other chips of the same type, peripheral circuits include power supplies, on-chip clock oscillators and other types of chips required for high integration, fast response, anti-interference ability. Reduce the overall cost of the scale and improve overall performance and reliability. The chip and MCU chip back-end interface and programming is very simple, all from the pin drive control signals have no internal chip registers. The input selection switch can select any channel A or channel B, and its low noise programmable internal amplifier is connected. Channel programmable gain is 128 or 64, corresponding to the full range of the differential input signal amplitude of + - 20mV or + - 40mV. Channel B, parameter detection system has a fixed gain of 32. Two optional differential inputs Rene-chip programmable low noise amplifier with selectable gain of 64 and 128 Rene-chip voltage regulators provide power directly to external sensors and the on-chip A / D converter . Rene-chip clock oscillator does not require external components, if you can also use an external crystal or clock Automatic power-on reset circuit Simple digital control and serial communication: all controlled by input pins, no need to program chip registers Select the output data rate of 10Hz or 80Hz While suppressing 50Hz and 60Hz power interference Power Consumption (Including Power Circuit): Typical Operating Current: <1.7mA, Shutdown Current: <1 | §A? Operating voltage range: 2.6 ~ 5.5V Operating temperature range: -20 ~ +85C packing list 1 * HX711 load cell module 1 * pin header
