Weight Sensor(Load Cell)

Installation HX711py

git clone https://github.com/tatobari/hx711py.git
cd hx711py
python setup.py install

Raspberry PI BCM

(DT, SCK) : (20, 21)

How it works in robot

1. throw away the garbage, measure the weight, and send the value to the Mobius server
2. If the weight exceeds a certain value, move to the admin
