Is it possible to add a light sensor to a ruuvi tag?


Hi all, I just ordered a pack of 3 ruuvi tags, I have no experience yet about them so my question may be pretty stupid. I was wondering if I can ‘hack’ a ruuvi tag so that I can add a light sensor to it? Maybe by swapping out the motion sensor? of course I’d need to buy I small light sensor somewhere and attach it to the pins, but is such a thing feasible?



We’ve been considering adding a SMT photodiode / phototransistor to ADC pin and using ADC pull-ups, for example

but we haven’t had a chance to try it out or even simulate it just yet.


Thanks Otso. I guess I’ll wait till somebody has a done it already, don’t have the time to experiment with such things unfortunately.
