@Yveaux - I did try both at some point, but no joy. Sounds like i fried it before it could see anything.

Hi,

I bought a Panasonic PIR sensor hoping that they would be a reliable alternative to SR501. However, i am facing trouble understanding the pinout of the panasonic sensors. The Datasheet has not been very helpful.

From the datasheet, this is the pin out.

And my understanding is that this is the pin out.

The senor is however not responding. i have been confused about the pin out and might have fried the sensor already. Please guide of my understanding of the pi out is accurate.
