M5SCALE DIY Kit is a DIY kit of M5 that implements a digital scale, which makes it more of an Application-approach development kit.
The overall structure is made of acrylic material. The electronic part is the main controller, M5StickC, and a WEIGH unit.
A cantilever beam-sensor is used to detecting the bend over forced on top of the scale by object weight.
it will transfer the deformation into a voltage signal and as an input of the WEIGH sensor which will be captured and read by M5stickC.
Other than that, there also some small components that is included in the kit, you have the total freedom to assembly the whole thing and reprogram it as you like.
The software is open-sourced on GitHub, you can program it either with UIflow or Arduino.
The lego holes on bottom board allow you to place more M5 sensors for extension functions, Plus M5StickC is wifi available, you have the freedom to build something impressive.
