Overview

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

FAQ

1.How long do motion sensor lights stay on?

Most people set their motion detection lights so they will stay on for about one to two minutes.

2.Do motion sensors save electricity?

Motion sensing switches do have some “phantom” energy use. According to this study, motion sensor switches use about a watt of energy on standby mode (23 hours a day) and 5 watts on active mode (about an hour a day). This trims a bit off of your overall savings.
