Description
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 < 1.5mA, power down < 1uA
