- bschwindHN 8y agoFLIR for turning off a light in a room seems like a ridiculous amount of overkill. I don't know numbers off the top of my head but I feel like at that point you're using more energy for FLIR than the light itself. Not to mention the cost of a single FLIR sensor is probably pretty high.
- ehavener 8y agoI think clever placement of traditional IR sensors is the answer here.
