CK-7003 Passive Infrared Sensor Wireless Alarm System Kit
SKU: CK-7003
Overview
CK-7003 Passive Infrared Sensor Wireless Alarm System Kit
Turn on a lamp, siren, horn, etc, when a human intruder is detected by this kit. Uses a sophisticated PIR sensor that is fully assembled and a 433MHz receiver that you build. The PIR can detect the presence of a human at up to 40 feet away and transmit the intruder detection to the tiny 433MHz receiver kit that you build. The receiver consists of a pre-assembled front end 433MHz receiver module and a pre-programmed microcontroller IC circuit which must be assembled. The size of the receiver PC board is 2.05" x 1.35". It operates from one 9V battery (not included) and has a relay that can switch on your 120VAC lamp, optional sound bomb, or any device of your liking up to the current rating of the contacts. The receiver kit turns on devices for about 15 seconds each time an intruder is detected, then resets itself and waits for the next activation. The PIR sensor uses one 9V battery (not included) and can operate for up to a month before the battery needs to be replaced. The receiver unit can be activated by more than one sensor, so if you purchase more than one sensor you can protect various rooms, garage, etc, in your house. Receiver range to sensor is about 30 feet. Complete package containing one pre-assembled sensor, all parts, PC board and instructions to build the receiver. Skill level 2.
