Interfacing PIR sensor to 8051 microcontroller

Posted on Wednesday, May 13th, 2015 in Interface, sensors by DP


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.
