Bed occupancy sensor, using parts you have

Now I understand why some of you have padded your sensors. I have came up with my version since I don’t have any foam pads laying around.

I used the battery holder springs. Hot glue them to a plastic sheet and lay another sheet over it for some added padding since it is kinda pointy. Sandwich between the 2 foil sheets and include them in plastic folder.

I will report back to see if it is any better than my first attempt.

Update.1: Initial Test
Sensors seems to be working. Threshold numbers have changed of course. Also, the hot glue used to bond the springs is making this clicking sound when the spring wire rub against the glue. I place a piece of cotton between the two. Annoying clicks FIXED.

Threshold:

Top: 26
Middle: 23
Bottom: 30

I need to sleep on it over night to really test the springs if it will rebound back to it’s original position in an instant.
