Material Prepared :

• Chair
• Cushion
• Load cell (QL605D)
• HX711 module
• Arduino Uno board

 

Process :

1.Build up the load cell

 

2.Linking with the HX711 module and the Arduino Uno board

 

3. Put the whole circuit (loadcell, HX711 Module, Arduino board) on the chair then put one cushion next to the whole circuit to fix the position of the circuit & put one cushion on top to cover on it.
