I need help with a custom project of mine.
What is need is a small device (smaller the better) Want it around the size of a match box if possible.
I want it to be a motion sensor that i can put in a small box in my bedroom. Then whenever someone puts their hand in the box i want it to relay to a receiver which will be in another room of the house. I want the receiver to light up and stay lit up until i push a button on the receiver and also make some sort of sound like a doorbell.
The size of the receiver can be much larger than the motion sensor part of the device.
obviously i want all of this to be wireless and powered with small long lasting batteries.
Also if so, can you make it so it wont interfere with other devices if there is a few of them in the building?
Depending on the response i get, i only need the circuit plans for this project. If you can do both circuit plans and build it, let me know and we can talk about it in more detail
