How to Interface load Cell with Microcontroller

This straight bar 5kg load cell (sometimes called a strain gauge) with a complete assembly kit can translate up to 5 kg 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. This straight bar load cell is made from an aluminium alloy and is capable of reading a capacity of 0~5KG of weight

It has Four lead wires which can be connected to HX711 Load Cell Amplifier Module. It is easy to use with driving voltage 5-10V and produce the output voltage as per the force changes over it.

Features:
1. On-chip active low noise PGA with selectable gain of 3264 and 128
2. Simple digital control and serial interface: pin-driven controls programming needed
3. You need to connect load cell with HX711 module like this, Red to E+, Black to E-, Green to A+, White to A-
4. This HX711 module uses 24 high precision A/D converter chip HX711.
