Fridgebit - is there such a thing yet?

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 :blush:

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.

Sounds like something an Estimote could do.

If you put a beacon in the fridge, when you open the door, it will be able to connect to your smartphone - assuming the phone senses it while the door is open, which could be as little as 5 seconds.

Perhaps even better, attach an estimote sticker to the door and create an action based on its motion sensor.

Thanks! Not sure if they have Android compatibility yet but looks really cool. Would be really nice if I can interface it to rfo-basic for rapid prototyping.

The idea that comes to mind here is to purchase a smart light bulb to replace the standard bulb in your fridge. I know that many will allow you to monitor when and for how long they’re on.
