Tired of fumbling for a light switch in a dark closet, pantry, or hallway? Or maybe you want to build a cool, automatic under-cabinet or stair light? This tiny PIR motion sensor switch is the brain you need for your DIY lighting projects. It's super small (about 2 inches long) and works by detecting the infrared heat from a moving person – so when you walk into its range, it automatically turns your connected lights on. After you leave, it waits for a bit (the delay time is adjustable, default is 15 seconds) and then turns the lights off. It's a fantastic way to save energy and add convenience.
It's really versatile power-wise. You can run it from anything with a USB port – a phone charger plugged into the wall, a power bank, or your computer's USB – and it accepts a wide input voltage from 5V all the way up to 24V DC. The output can handle up to 5 amps, so it can power a decent amount of LED strip lights or other small DC gadgets. The sensing angle is 120 degrees, and it can detect motion from about 5 to 7 meters away. It even has a built-in chip to help it work consistently in different temperatures. Perfect for automating lights in garages, storage rooms, bathrooms, or even inside a cabinet. The black color is discreet. Just wire it between your power source and your LED lights, and you're set for hands-free illumination!
