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. This kind of long distance pir sensor are small, inexpensive, low-power, easy to use and don't wear out. For that reason, the long range pir motion sensor 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 long range pir sensor for lighting 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.
Among those pir sensor manufacturers, senba sensing technology co ltd has become the first owner of this special technology enterprise in China.
