Good sensitivity, needs calibration
The module detects motion well, but I had to spend some time calibrating the delay time to prevent false triggers from my ceiling fan. Once set up, it has been reliable.

Excellent build quality
The PCB looks clean and the soldering points are solid. I integrated this into a smart lighting system, and it responds instantly to movement. Highly recommended for hobbyists.

Perfect for my Arduino project
This sensor works flawlessly with my Arduino Uno. The sensitivity adjustment pots are very responsive, and the detection range is accurate as described. Great value for money.

Reliable for indoor use
Works great inside the house for hallway lights. The 120-degree angle covers the whole corridor. Just note that it is designed for indoor temperatures and might need shielding if used outdoors.

Decent but range varies
The sensor works, but the 7-meter range seems optimistic in a cluttered room. I get about 5 meters reliably. Still, for the price, it is a decent component to have in the kit.

Great for learning electronics
Bought this for a university project on smart homes. The documentation online is plentiful, and the module itself is very forgiving to wire up. It worked on the first try.
Q: Can this sensor detect motion through glass?
A: No, PIR sensors cannot detect infrared radiation through glass or solid walls. The lens must have a direct line of sight to the moving object.
Q: Does this come with a Fresnel lens installed?
A: Yes, the white dome-shaped Fresnel lens comes pre-installed on the module to focus infrared signals onto the sensor element.
Q: What is the difference between the two potentiometers on the board?
A: One potentiometer adjusts the sensitivity (detection distance), and the other adjusts the trigger delay time (how long the output stays high after motion stops).
Q: Can I use this to trigger a 220V light bulb directly?
A: No, this module outputs a low-voltage digital signal. You must use it to trigger a relay module or a transistor circuit that can safely handle high-voltage loads like light bulbs.
Q: Is this module compatible with Raspberry Pi?
A: Yes, it is fully compatible. Since the output is 3.3V logic, you can connect the OUT pin directly to a GPIO pin on the Raspberry Pi without a level shifter.
