![]() Today we're going to be setting up our motion sensor then testing it by moving our bodies. These sensors are commonly used in home alarm systems - if your home has an alarm, have a look in the corners of the ceilings and you may see something similar. PIR sensors detect movement via the heat energy (Infra-Red radiation) given off by humans or animals. The sensor in your kit is a PIR sensor, which stands for Passive Infra- Red. We can code this in a similar way to the buttons from day #3 as a trigger for our program. This is a digital sensor, giving us a HIGH signal if movement is detected. Today we're going to be using a sensor that detects motion, allowing our Pico to react to things like people and animals when they are near our project. ![]() Welcome to day seven of your 12 Projects of Codemas Advent Calendar.
