Digoo Door Sensor

thingiverse

These door/window sensors are great except if the tamper switch at the back isn't making perfect contact with the surface it it attached to. If you use screws to attach to a wooden door frame or door then it works fine. If you are attaching to a metal door, window or gate you probably want to use the supplied adhesive strips. This is the problem. The sensor might be well fixed in place, but the tamper switch is not pushed in all the way. It only sends Open and Close RF433 signals, not a separate signal for "Tamper". If the tamper switch activates, the sensor sends the Open signal which is pretty useless. I designed this basic base to be glued to the underneath of the sensor to keep the tamper switch closed. You can then use the adhesive strip or hot glue to attach to the door, window or gate. Printing: Printed at 100% infill
