M5Stack® Mini Weight Module HX711 Sensor 24 Bits Weighing Pressure Sensor I2C Interface for Audrino Grove Port

Description: WEIGHT intergrates an 24 bits A/D chip HX711 that is specifically designed for electronic weighing device. 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 analog power supply pin. Channel B has a fixed gain of 32. There is no programming needed for the internal registers. All controls to the HX711 are through the pins. In the test, we have this Unit channel A to connect a pressure sensor. Then use M5Core screen to display the weight data. Product Features: Two selectable differential input channels On-chip active low noise PGA with selectable gain of 32, 64 and 128 On-chip power supply regulator for load-cell and ADC analog power supply On-chip oscillator requiring no external component with optional external crystal On-chip power-on-reset Simple digital control and serial interface: pin-driven controls, no programming needed Selectable 10SPS or 80SPS output data rate Simultaneous 50 and 60Hz supply rejection Current consumption including on-chip analog power supply regulator: normal operation
