I was thinking that it would be cool to track the number of times I open my fridge each day. This would probably be a simple task for a smart connected fridge but I was wondering if anyone has thought of a simple way to equip a run-of-the mill old fridge with a sensor. I was thinking of maybe using something like a magnetic switch connected to an Arduino or just a simple counter circuit of some sort.
I attempted making a “FridgeBit” app using a very old smartphone that was no longer useable:
It works somewhat well but it would be a pain to have to charge it every day.
I am thinking that the number of times that the fridge door opens would be a simple useful statistic for single people or a couple or chronic overeaters like me
I’ve tried scouring eBay for Bluetooth switches etc. but haven’t yet found anything that quite fits the bill. It obviously would be very cool if it had a Bluetooth interface but even a simple counter display would probably work too.
