HALJIA Digital Barometric Air Pressure Sensor Module 0 40 KPa Water Level Controller Board Liquid Flow Compatible with Arduino 3.3V 5V

The HX710 is a 24-bit A/D converter chip designed for high-precision electronic scales with high integration, fast response, and high immunity to interference. The input low noise amplifier has a gain of 128, when the reference voltage VREF is 5V, the corresponding full-scale differential input signal amplitude is ±20mV. The clock oscillator inside the chip does not require any external devices. The digital temperature sensor on the HX710A chip can directly read the inside of the chip, that is, the temperature inside the system. HX710B can be used to detect battery voltage by detecting the voltage difference of DVDD-AVDD. All control signals are driven by pins and there is no need to program the registers inside the chip. The MCU requires only two I/O ports to achieve all control of the ADC, including power-down control.
