Works better than PIR

Great sensitivity, detects through thin plastic covers which my old PIR sensor could not do.

5 FAQ

Q: Is it compatible with ESP32?

A: Yes, it operates at 3.3V logic levels which are compatible with ESP32.

Q: What is the maximum voltage input?

A: Please do not exceed 5V DC to avoid damaging the module.

Q: Can this detect motion through wood?

A: Yes, microwave signals can penetrate non-metallic materials like wood and plastic.

Q: Does it work in complete darkness?

A: Yes, it does not rely on light or heat like PIR sensors, so it works in total darkness.

Q: Can I adjust the sensitivity?

A: The standard version has fixed sensitivity, but some variants include a potentiometer.
