You can use a piece of cardboard from any old box to mount the sensor. Check out the below guide for some great tips on cutting cardboard and more.
- Cut out a piece of cardboard to be roughly a 2" x 7" (5cm x 18cm) rectangle.
- On the right side of the rectangle, using a ruler, draw a square to be sized exactly 7/8" x 7/8" (22mm x 22mm).
- Take the PIR sensor and pop it into the cardboard hole you just cut out.
- The sensor should be as close to flush as possible with the PCB of the sensor.
- Fold the cardboard in half along the midpoint.
- Add some tape to the back of the sensor to secure it in place.
- Place a few pieces of double-sided tape on the back of the cardboard on the other side of the sensor.
- If you don't have double-sided tape you can also use thumb tacks
- Pick a spot in a corner of the room you are monitoring and mount the sensor with double-sided tape or with thumbtacks.
- Use the fold in the cardboard to angle the sensor such that it is facing at about a 45-degree angle inward towards the room.
- Make sure the sensor is placed about 3 - 4 feet above the ground and not obstructed in any major way.
- Find a good spot close to a power outlet and the mounted sensor to place the FunHouse
- Power up the FunHouse using the USB-C cable and the 5V power adapter.
- Plug the sensor in, making sure the red wire from the JST cable goes to the 5V side of the sensor.
That's it! You're ready to track the room's occupancy status! Give the sensor a minute or two to acclimate and calibrate before trusting its accuracy. You can adjust the sensitivity and the length of time the sensor is triggered by adjusting the potentiometers on the back of the sensor with a Philips head screwdriver.
