Load Cell
Feature
4 leads, easy to use, plus 5-10V drive voltage, direct output as a voltage signal due to force changes. Works for arduino and raspberry pi.
Installation method
1. One end of the sensor is fixed by a screw hole, and the other end is left in the air.
2. Apply force in the direction indicated by the label.
3. You will retrieve consistent pressure values from the load cell, if you mount the load cell on something that is soild and heavy.
4. Please be careful not to directiy press the white latex part to avoid damage to the sensor.
Using a Single Load Cell compatible with Arduino
Connect RED wire of load cell to E+ of hx711 module.
Connect BLACK wire of load cell to E- of hx711 module.
Connect WHITE wire of load cell to A- of hx711 module.
Connect GREEN wire of load cell to A+ of hx711 module.
Connect GND of hx711 module to board GND, and VCC to board 5V pin.
Connect DT and SCK of hx711 module to any digital IO pins of board.
HX711 AD Module
Parameter
1. The module uses 24 high-precision A/D converter chip hx711, is designed for high-precision electronic scale and design, with two analog input channels, the internal programmable gain amplifier integrated multiplier 128.
2. The input circuit can be configured to provide a bridge voltage electrical bridge (such as pressure, weight) sensor model is an ideal high-precision, low-cost sampling front-end module.
3. Operation supply voltage range: 2.6 - 5.5V
Operating Temperature Range:-20 degree ~ +85 degree
Features
(1)Two selectable differential input channels
(2)On-chip active low noise PGA with selectable gain of 64 and 128
(3)On-chip power supply regulator for load-cell and ADC analog power supply
(4)On-chip oscillator requiring no external component with optional external crystal
(5)On-chip power-on-reset
(6)Simple digital control and serial interface: pin-driven controlsno programming needed
(7)Selectable 10Hz or 80Hz output data rate
(8)Simultaneous 50 and 60Hz supply rejection
(9)Current consumption including on-chip analog power supply regulator: normal operation < 1.7mA, power down < 1uA
How to change the rate of HX711?
When you have the XI pin grounded, then the RATE pin controls this, RATE=1 for 80SPS, or RATE=0 for 10SPS.
