Applications

Ceiling Light

The PIR motion sensor adopts high-performance infrared detector. As long as human cross through its detection range, the infrared switch generates an electrical signals.

FAQ

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

2 . What detailed information do we need to provide if we want to place an order for PIR sensor ?

You need to know the following info:

- Output signal (Digital type or Analog type)

- AMDtype or plug- in type

- The pins for PIR(3pins, 4pins, 6pins)

- (such as 4-20mA)
