Interfacing Load Cell With Arduino Using Hx711

In this post we are going to learn about strain gauge based load cell.

Strain gauge load cell circuit diagram. There are several types of strain gauge load cells. The four wires of the load cell or strain gauge are connected with the hx711. A strain gauge is a device that is used to measure the strain that occurs in an object. We will be exploring what strain gauge is what load cell is temperature effect on strain gauge temperature compensation with wheatstone bridge and load cell amplifier hx711 and finally we will learn how to build an arduino based weighing scale machine by implementing load cell as the weight sensor.

From the resulting data can be easily determined using the equation above. The device was invented in the year 1938 by edward e. R l is the lead resistance. As you can see in the connections diagram.

Gf is the gauge factor which should be specified by the gauge manufacturer. The device is still being used in many electronic circuits mainly as the principle sensing element for sensors like torque sensors pressure sensors load cells and so on. The red wire of the strain gauge or load cell should be connected with the e pin of the hx711 break out board. Common types of load cells.

E s is the simulated strain. A strain gauge is a passive transducer that converts mechanical displacement into the change of resistancea strain gauge sensor is a thin wafer like device that can be attached to a variety of materials to measure applied strain. R g is the nominal gauge resistance which should be specified by the gauge manufacturer. When force is exerted on the load cell the structure and resistance of the strain gauges changes and is measured.

Hi friends in this article i am going to describe you strain gauge working principle gauge factor and strain gauge load cell working. In a load cell the resistors are replaced with strain gauges and arranged in alternating tension and compression formation. Wheatstone bridge technical specifications and infomation. The four wires of the load cell should be connected in the correct way otherwise this will not work.
