Product Description
Load cell is an instrument that helps to determine size of a load (either a force or weight) and converts mechanical force into digital output.
It consists of a metal core and a set of electrical resistances that transform when a force is applied to it. But it returns to its original state after force removed.
It have many purposes, including telling weight of something, weight change over time and measure strain and load on a surface. It's perfect for electronic scales, digital scales, electronic balance and many commercial scales weight involved.
To use a load cell, you need first calibrate it where you can increase or decrease calibration factor units to get your correct weight using a microcontroller.
Frequently Asked Question
Q:What is the range of output? how low will it accurately go? i need accuracy to at least 200g, preferably lower
A:The accuracy depends mostly on the ADC resolution, 24Bit in the case of standard HX711, accuracy will be better than 200g even with 50KG load cell, it will be in the order of few grams at most
Q: How accurate can I measure items? If I use more than one cell does the accuracy improve or degrade?
A: this type of cell, which is 50kg half bridge will provide a typical accuracy of 50 to 100g with a maximum range of 200K for 4 cells. Adding more cells will increase the maximum load and decrease accuracy.
Using a Single Load Cell 1x50kg by Adding 2 Resistors
Connect outer wire(white and black) of load cell to E+ and E- outputs of hx711 module.
-Connect middle cable(red) of load cell to A+ input of hx711 module.
-Connect two 1k resistors to A- input of hx711 module. Then the other end of resistor to white and black wires.
-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.
Using Two Load Cells in a Singel Circuit 2x50kg (100kg)
-Connect opposite sides of outer wires(white and black) of two load cells.
-Connect outer wire pairs to E+ and E- output of hx711 module.
-Connect middle wire(red) of load cell to A+ and A- inputs 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.
Using 4 Load Cells in a Single circuit 4x50kg (200kg)
-Form a loop by linking same color outer wires(white and black) of the four load cells.
-Connect middle cable(red) of one of the diagonals to the E+ and E- outputs of the HX711 module.
-Connect the other diagonal to the A+ and A- inputs of the HX711 module.
-Connect GND and 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.
