Thanks, negitron, at least I now know what a FET is, having looked it up. It also looks like I'll have to find a friend who knows how to crack things open and wire things up. Thanks.

skeptic2, thank you for your response. I looked at the alertelectrical site you offered, which seems to deal with these sensors as they would be used in a proper intruder alarm system. The Rokonet sensors I have display three lateral leds of different colours. When powered up the sensor will...

negitron, thanks for the response. I have only a very basic knowledge of electronics. The sensors are not intended to be incorporated as a proper alarm, but merely to detect and alert to movement in a defined area by momentarily lighting a lamp or sounding a buzzer, and then to go quiet when...

I have four dual technology (alarm type microwave & pir) sensors, which I would like to wire up as motion sensors that operate a light or buzzer only during the period of detection. The sensors are Rokonet brand, model RK815DT, which display three frontal leds: m/wave, pir, alarm trigger. They...

I am a new member. Would I be out of order introducing a question on microwave detection sensors into this thread?
