![]() In the sketch above, I drew the connections basing on my PIR model, the SE-10. So, before making any connections, it is important that controls the datasheet of the model in possession. In the previous article you had seen that the color, the functionality and the arrangement of the three output cables may vary depending on the PIR model. So you have to build a circuit basing on the sketch below. But this time, you will see a Raspberry Pi in place of the Arduino. ![]() You will then begin, precisely from the point at which the previous article had been interrupted, that is, with the connection diagram realized with the Fritzing software. This is the second part of the article published about a week ago that concerned the PIR motion sensors, explaining the technical details on their usage and operation (see here). In this article, continuing with the topic, you will see how to use them in a more practical way, or better, by using a Raspberry Pi board (in my case a Raspberry Pi Model B+). ![]()
