Need advice for creating nS time delay

Ingvar,

I tested your code a minute ago; with some additions;

Congratulations! It works flawlessly.

My code is almost the same as yours.

What I see here is that, when we set the pin HIGH and then LOW, the time it takes to set the pins is already good enough for the sensor reading.

Good to know that we have working code ... if i ever buy one of theese PIRs.
