Kit makes an Infrared Sensor that can detect the radiating body heat of a person or animal or infrared light. Detection of body heat can be sensed up to 18 feet away from the unit. The unit can be set up to set off an alarm or lights as desired. The unit uses PIR (Pyroelectri Infrared) sensor technology. You could even set this circuit up to turn on your railroad or model scene when someone stands in front of it!

Kit comes with complete with circuit board, components, instructions. Operates on 12volts DC. Relay can switch AC or DC up to 240 volts 500 watts. Requires basic soldering skills and a 15 to 30 watt soldering iron. Solder is included

Uses optional enclosure FB05
Circuit board is 1.74" x 4.88" long
