Hey everybody let's have a fun discussion about creative ways to integrate Lux / Luminence sensors into the mix.
My mind will be thinking of the Phillips Hue Outdoor Motion Sensor for my thoughts, but any Lux sensor should work as well.
Mailbox notifications can be achieved by measuring the lux levels when the mailbox door is opened. May not work in the winter if you have very late mail deliveries. The Hue Sensor could fall back on it's motion detection, which is not affected by heat.
Fridge notifications - A lux sensor could sense when the door is left open by either seeing the light through the crack in the door, or just when the fridge bulb turns on. Bonus here for the Hue, it could also measure the temp to let you know when your fridge is too warm...this combo can tell you why (fridge broken, or door left open)
Very iffy would be mounting a Lux sensor very close to a device that has LED warning lights or such. Not exactly sure if they would trigger lux, but I would think so. Could be for dishwasher done, Microwave done, smoke alarm batteries need changing. Who knows, this one is definately more of an experiment.
That's just a few that comes to mind. Obviously some of these could be accomplished with other sensors, but sometimes that just doesn't work. So be creative. What could you use Lux sensors for?
