Long Distance 12M Detector Sensor HM412 From Senba Factory

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 sensorare small, inexpensive, low-power, easy to use and don't wear out. For that reason, the long range pir motion sensorare 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

Most people set their long range pir sensor for lightingso they will stay on for about one to two minutes.

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 ltdhas become the first owner of this special technology enterprise in China.
