Praveen from CircuitsToday has written up an article on interfacing PIR sensor to 8051 microcontroller:

PIR sensors are widely used in motion detecting devices. This article is about interfacing a PIR sensor to 8051 microcontroller. A practical intruder alarm system using PIR sensor and 8051 microcontroller is also included at the end of this article. Before going in to the core of the article, let’s have a look at the PIR sensor and its working.

    Did anyone actually read the linked article? Did your eyes bleed as well? :-P :-P
    Notice he did not explain R4. I would love to hear his explanation for R4. :-P :-P

    Lots of care taken to create a specially boring circuit – and takes some skill to create this level of sleep-worthy article. And useful code, written in assembly so portable. All round a great project.
