Simple and easy-to-use sensor

Ideal for use with Raspberry Pi. Wide input voltage range, no adjustments. The output is always 3 volts regardless of the power supply. You're not driving the LED directly, so use a 2222 transistor or similar for this test. Sensitivity is better at 5V or higher than 3V. Everything worked for me out of the box. I'm packing something to play with the cat!

Pros

Durable finish

Cons

Cable is shorter than other picks

I've used this product to repair a LED battery closet light with a defective PIR sensor.
