This wide bar load cell (sometimes called a strain gauge) can translate up to 40kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar. With this gauge you will be able to tell just how heavy an object is, if an object’s weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface. Each wide bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 10kg. These load cells have four strain gauges that are hooked up in a Wheatstone bridge formation. The color code on the wiring is as follows: red = E+, green = O+, black = E-, and white = O-. Additionally, these load cells offer an IP65 protection rating and feature four M6 sized thru holes for mounting purposes.

1 x Weighing Load Cell
The electronic weighing machine uses load cell to measure the load or pressure produced by the load, here most load cells are following the method of a strain gauge, Which converts the pressure (force) into an electrical signal, these load cells have four strain gauges that are hooked up in a Wheatstone bridge formation.
When we apply load to the strain gauge resistance will change and hence the output voltage from the load cell get changes by the way we can measure the load value.
Wheatstone bridge formation of Load Cell
HX711 (24 bit Analog to Digital Converter)
HX 711 is a precision 24-bit analog to digital converter (ADC) specially designed for Weigh scales and industrial control applications to interface directly with a bridge sensor.
Simply connect Load cell wires to the HX711 module based on their color, then connect DAT (Data) pin to Arduino Analog pin A1 and connect CLK (Clock) pin to Arduin0 Analog pin A0, Put Vcc and Gnd supply from Arduino power source pins.
