Since a PIR sensor allows to detect motion, it means that we can use it to know when someone enters and leaves a certain area. That information can be useful, for example, to trigger an alarm or to turn on the lights, amongst many other possible application scenarios. PIR stands forPyroe...
The moving objects are detected by the PIR motion sensor which send the signal to Arduino which again sends the signal to piezoelectric buzzer. The piezoelectric buzzer starts playing the predefined alarming tune. Also, an LED is turned on as soon as the motion is detected. A one way ...

The PIR motion sensor can detect people if in the area, then alarm triggered. Component required Grove Beginner Kit MINI PIR motion sensor Hardware Connection Please follow the same color line to connect each sensor on the board, put the PIR motion sensor grove cable to the D2.Assembly...
By far the biggest challenge I had during this project was figuring out how to detect goals. Each player has their own net, and their own ball return slot, so that made my life a little easier. My first idea was to use a PIR motion sensor (like you’d find in a home alarm system...
