PIR sensor module is an ideal device to make efficient alarm systems and save energy lights. Let us see how it works?
Install this Deterrent Light in your Home backyard and Porch to thwart the attempt of Burglary. This PIR Motion Sensor based light switches on instantly when it detects a Human movement from a distance of ten meters. The light turns on for 3 minutes and then turns off. It Re triggers again if the movement continues. Relay is used to drive the load, so any kind of lights can be used.
PIR Motion Sensor Modules are now available at low cost and it can be used to make Motion sensor alarms, PIR light switches etc. It requires only a few components and within few minutes, you can make a highly useful gadget for your home. Let us see the details of PIR Module and the circuits.
PIR Sensor Module is one of the new introductions in electronics which is a highly useful device to switch on lights when it detects a human movement. It turns on the lights from 30 seconds to 3 minutes depending on the preset adjustments. Its range can be as high as ten meters which can also be adjusted. The module gives a high output when it detects the human movement. This high output can be used to drive a relay through a switching transistor. Let us see the details of PIR sensor module.
