The solution box is brown box that has the PCB inside it. It is made of MDF (medium density fibre) and has an acrylic cover on it.

  1. After connecting the sensors, wind the wires in the box this way so that you don't accidentally pull and disconnect the sensor from the board.

  2. The solution box has 3 holes at the back. Use them to install your solution on a steady surface.

    You may use the left and right holes for hanging on 2 nails, or use just the centre hole to hang the solution box on 1 nail (if the box is stable enough on one nail).
