Introduction: Tutorial: How to Calibrate and Interface Load Cell With Arduino UNO

By Mybotic

Hi guys, we will be showing you tutorial: How to calibrate and interface load cell or HX711 Balance Module with Arduino UNO.

Description about HX711 Balance Module:

This module uses 24 high-precision A / D converter. This chip is designed for high-precision electronic scale and design, has two analog input channels, programmable gain of 128 integrated amplifier. The input circuit can be configured to provide a bridge voltage electrical bridge (such as pressure, load) sensor model is an ideal high-precision, low-cost sampling front-end module.

Specification about HX711 Balance Module:

  • Two selectable differential input channels
  • 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
  • Data Accuracy: 24 bit (24 bit analog-to-digital converter chip)
  • Refresh Frequency: 10/80 Hz
  • Operation supply voltage range: 4.8 ~ 5.5V
  • Operation supply Current: 1.6mA
  • Operation temperature range: -20 ~ +85℃
  • Dimension: Approx. 36mm x 21mm x 4mm / 1.42" x 0.83" x 0.16"
