Description |
This kit lets you monitor door openings and movements passed near a certain point. The circuit is built around a matched pair of ceramic transducers which convert movement energy to electrical energy and vice versa. Circuit is crystal locked by 40Khz crystal for maximum effciency. Any movement in the area scanned by the transducers will be deteched and a pulse is produced.
In this kit the pulse turns on a LED. Pads are provided to take thgis pulse to add on circuits where it may turn on buzzers, lights, etc. The unit will work reliably from 12 to 24 feet depending on the sensitivity setting and the direction of the movement. The circuit uses 9V to 12V not included. Board size is about 1/2" x 2 3/4" (receiver-transmitter) 2 3/4" by 2 3/4" (movement detector). Kit contains over 50 components, schematic, and screened PC boards.
Order No. 80-200. Can ship in 3-5 days.
