For those of you who have smoke detectors installed in your home, you've probably already experienced a false alarm, followed by a desperate and runny sound.
After all, it's also hard to turn off, so don't be surprised if you end up with a few more gray hairs as a result. But we need it, that's why they are with the company Nest Labs developed a uniquely designed LED light effect that warns of danger. In the case of green, the air is clean, yellow warns of potential danger, while red requires immediate action. In case you miss the warning light, you can Nest Protect also sync with your smartphone or tablet.
