DT-205 uses ATMEGA8L

The DT-205 is a “dual technology” motion sensor. What this means is that in addition to passive infrared (PIR), the DT-205 also utilizes ultrasonic sensors. After setting up the motion sensor and playing with it a bit, my curiosity got the best of me (as it always does) and decided to crack this thing open. What a pleasant surprise to see an ATMEGA8L proudly sitting there as if it knew I’d be looking. Looking, poking and proding, I am.  So there is the AVR in its natural habitat, i didn’t even poke around at the ISP yet. Well, that’s the complete board.  Not much to it: Power conditioning, PIR, Ultrasonic transducers, some analog front end circuitry, and the AVR. This is definitely getting some attention.  More to come later.
