The receiver and sender can be placed up to 20m . Extremely simple to set up Switch on the transmitter, line up the receiver (up to 20m away) and switch on.

Ideal for shop entrances, workshop doors or home security.

This circuit uses invisible infrared light to detect the movement of people through the door.

IR based security alarm circuit can detect any movement and trigger the alarm.

This circuit is very useful in homes, banks, shops, restricted areas where an alert alarm is needed on any movement. They are usually used in situations where it is impractical or not cost effective . Dual beam helps to reduce false alarms. Both beams require breaking before the alarm is triggered. Infrared and Ultraviolet Fire Detectors.

Single beam detectors give false alarms caused by birds,leaves etc. A PIR sensor measures infrared light that is reflected off moving objects that emit heat. They are commonly used to detect movement of people and animals to trigger alarms and security lighting. The sensor beams create an invisible field that sounds an alarm if someone strays into it. Excellent for protecting specific areas around your home.

By using infrared technology, these devices can sense . Kip Kipkay Kedersha is known for his intriguing and clever how-to and prank videos, even when he teams up with MAKE Magazine. He will show you how to tweak, hack, mo and bend any technology to your hacking needs. In this case, the advance, the thermal imager, and video alarm system on there!

Reliable low cost perimeter security system uses active infrared photoelectric beam detectors, long range 300m protection, low-false alarm rate, outdoor installation. Home Security Wireless Pet Friendly Alarm PIR 40ft Motion Detector Sensor. This product is the high stability of wireless infrared detector. Not only will the motion-sensing alarm protect your gear from animals and zombies alike, the project can help you get started with Arduino. The alarm gets triggered and beeps continuously till the time the circuit is reset.

Free 2-day shipping on qualified orders over $35. Here we use an IR LED and an IR photo diode. When the IR rays falls on the IR sensor the circuit remains si. The passive infrared (PIR) motion detector is one of the most common sensors found in household and small business environments.

It offers affordable and reliable functionality.
