Transmitter/receiver pair serves as antitheft alarm
Design How-To  
3/8/2012   3 comments
Simple circuit consists of a transmitter/receiver pair that functions as an automobile antitheft alert system. When the vehicle leaves the area, this circuit sounds an alarm because the distance between the transmitter and receiver increases and the received power level falls below a predetermined threshold.
