In this mini blog series we will build an IoT based intruder detection and alert system.   Blogs: Part1 : Connecting Pir Sensor  <--- this blog Part2 : Capturing intruder image Part3 : Email Alerts     In this post we shall connect a simple cheap Pir motion sensor to Riotboard. We will be using Pir sensor HC-Sr501.       Pir Sensor HC-Sr501 has pins : VCC, GND, OUT. VCC will be connected to pin2 (5VIN) in J13 expansion port. GND will be connec ...
