This Kit includes a weight sensor that has a capacity of 20kg, and the mechanic parts to install the weight sensor, ready for an electronic scale application. As you know, the most difficult parts in developing such an electronic scales is the mechanic parts and A/D parts, we help you solving the whole problem by providing you all the mechanic parts and the Data acquisition parts. You can collect the data with any microcontroller include Arduino board. The Weight sensor outputs differential signal, with the Green wire (+) and White wire (-). Strongly recommend the HX711 Board
to amplify and sample the weight result.
