The unit has five main hardware components and a printable case. Links for electronics and 3D printed parts are provided below.
Step 1: Use JST cables to connect port 0 of the Phidget to the temperature output and port 1 to the humidity output.
Step 2: Connect the light sensor to port 2.
Step 3: Connect the motion sensor to port 3.
Step 4: Fit the Phidget board on to the four pins of the case so that it lies flat.
Step 5: Slide the three sensors in to their corresponding slots in the case.
Step 6: Put each of the two pins in the holes of the round lid.
Step 7: Fit the lid over the wires and press it firmly in to position, making sure it is completely flush against the case (You may have to squish the wires a bit!)
Step 8: Cover the Phidget with the back piece. This locks the lid in place to complete assembly.
