Is there a LED inside the detector, like in some burglar alarm detectors? I am asking because I have my 12V power supply connected to "+" and "-", and I don't see any changes in the middle pin "out", it just stays low (0V). Trying to tell if my device is DOA or not.
No problems, though, as 3.3V is correctly read as HIGH by 5V logic.

See below - the output appears to be 3.3V HIGH, not TTL, regardless of power supply voltage. At least for my unit. No LED in the sensor.
This sensor gives a digital signal or analog in output?? It gives HIGH and LOW or another type of signal??
Thanks
Hi,you will get a TTL HIGH(or LOW)level from output.

I used a simple 555 timer circuit and an LM7805 along with a relay and a 12VDC wallwart to build a automatic closet light...super simple to use.

ouput is high for 2.15 seconds in L mode (jumper setting) and 4.15 seconds in H mode, which is a bit long for my application. The sensor work great though...
If anybody could help me with a more responsive sensor (_10$) I would appreciate it :)

Garrett's right, the sensors are very quick to setup and easy use. They can detect large movements at around 20 feet. And I haven't found PIR modules for cheaper.
