The right switch for Raspberry Pi

by Gardener on Thu Jul 16, 2020 5:49 pm

I am looking for info on a switch or other sensor that can help me. I want to sense when a bee hive frame is put on a stand. The idea is that they switch would take a photo when triggered. My first thought was to use some sort of button that gets pushed when the honey bee frame is put on the stand. I have a couple of these Tactile Switch Buttons https://www.adafruit.com/product/1119 but they require to much force (or weight) to push easily. If the frame has no honey in it there is not much weight.

I am looking for something that senses either when the frame is close or can be pushed with a sensitive touch. Incidentally, I also saw a foot switch https://www.adafruit.com/product/423 which might work if I wanted to 'manually' trigger my camera but I did not see anything on the page about using it with raspberry pi.

Any ideas that would work to accomplish this would be appreciated.

This might work. https://www.adafruit.com/product/4540. How heavy are the frames when they're empty?

Also, you can wire the footswit ch like you would any other swit ch. This guide explains what pins to use, so just take them and connect them to a gpio and ground pin and you should be set. https://learn.adafruit.com/bluefruit-bl ... pedal-swit ch/wiring (you'll have to combine the url, it wasn't letting me put it as one url for some reason)
