PIR (motion) sensor

PIR motion sensors are great for detecting movement of pets or humanoids from up to 20 feet away - it might even work on zombies, though we can't guarantee that! This sensor has adjustable delay (about 2 - 4 seconds) and sensitivity. We'll also give you a 1 - foot (30 cm) cable with a socket, making it easy to reposition or mount using the two side holes. It runs on 5V - 12V power. If you need 3V, you can bypass the regulator, but it requires some soldering. The digital signal output is 3.3V high/low, and it has a sensing range of about 7 meters in a 120 - degree cone. Check out the PIR sensor tutorial page for wiring diagrams, CircuitPython and Arduino code examples, and project ideas.

Using this PIR motion sensor is easy. First, connect it to a power source that provides between 5V and 12V. If you need to use 3V, you'll have to do a bit of soldering to bypass the regulator. The 1 - foot cable with a socket allows you to place the sensor where you need it or mount it using the holes on the sides. Adjust the delay and sensitivity according to your needs. The sensor can detect movement from pets or people up to 20 feet away. Just be aware that if you want to run it on 3V, you'll need basic soldering skills. For maintenance, keep it clean and free from dust. Check the wiring regularly to make sure there are no loose connections. If you want more in - depth guidance, refer to the PIR sensor tutorial page.
