Description
- HX711 load cell amplifier
- Internal 24bit ADC amplifier
- 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
- Output sensing range depends on input voltage. For exmaple if input voltage is 5V, then full sensing range is 5V * 1mV = 5mV
- The higher pressure force, the higher output analog voltage.
- Common gauge load cell, version 1KG
- Wiring from HX711 to load cell:
- Load cell sensor RED — HX711 E+
- Load cell sensor BLACK — HX711 E-
- Load cell sensor WHITE — HX711 A-
- Load cell sensor GREEN — HX711 A+
- Wiring of HX711 to MCU Pins:
- Gnd — power gorund
- DT — data output
- SCK — clock
- VCC power 2.7-5V
