Function:
The car park indicator has a transmitter unit which is a passive infrared sensor. When the transmitter unit detects thermal infrared signals (e.g.,moving vehicle/person), it will send wireless signals to the receiver unit. The receiver unit will emit "ding-dong, ding-dong" sound and the LEDs will flash twice to warn you that you are parking too close to the wall. (Can also be sued as an indoor home alarm system).
