Good quality, fast shipping

The sensor works well in my home automation project. Took off one star because the pins were slightly bent upon arrival, but easy to fix.

Reliable performance

I bought five of these for a batch of motion detectors. All of them tested perfectly with consistent detection ranges.

Excellent value

Much cheaper than buying a whole new module. Saved my project and works just like the original factory part.

Perfect drop-in replacement

Worked exactly as expected for my RE200B module repair. The sensitivity is spot on and installation was straightforward.

Solid component

Does the job for replacing old sensors in legacy alarm systems. Just ensure your voltage regulator is stable for best results.

5 FAQ

Q: Is this compatible with the HC-SR501 module?

A: Yes, this sensor is a direct replacement for the PIR element used in the HC-SR501 module, provided the pin layout matches your specific board version.

Q: How do I identify Pin 1?

A: When looking at the bottom of the metal can, Pin 1 is usually marked by a small dot or notch near the pin. Please refer to the datasheet for the specific RE200B/D203S pinout diagram.

Q: What is the maximum detection distance?

A: The detection distance depends on the Fresnel lens used in your module, but typically ranges from 5 to 7 meters for human body detection in open spaces.

Q: Does this come with a Fresnel lens?

A: No, this listing is for the bare TO-5 pyroelectric sensor element only. The white plastic Fresnel lens is not included.

Q: Can I use this outdoors?

A: The sensor itself can operate within the stated temperature range, but it must be housed in a weatherproof enclosure with an appropriate IR-transparent window for outdoor use.
