20KG - Load Cell Amplifier, Weight Sensor Kit, HX711

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 20KG.
• 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
