PIR motion sensor saves Energy?
I have few projects interfaced PIR motion sensors, it is a real fun. In reality, you will find the PIR motion sensor commonly used in lighting system.For example, the lamp will be on when there are people walking. Planet green listed out some scenarios that motion sensor would help to save energy for you, but also pointed out that there is a case would waste energy. Huh? the argument is that the sensor consumes electricity, if you always remember to turn off the light in your room, then the power consumed by the sensor is not necessary:) But if you are absent-minded, install the sensor!
