Perfect for presence detection

Replaced my PIR sensors with these. The micro-motion detection actually keeps the lights on while I'm reading.

Good module, tricky config

Hardware is solid. Getting the UART commands right took some trial and error. Works great now.

5 FAQ

Q: Is 5V logic safe for the UART pins?

A: Yes, the module supports 3.3V to 5V logic levels on the communication pins.

Q: Can this detect motion through a plastic cover?

A: Yes, non-metallic materials like plastic generally do not block the 24 GHz signal.

Q: Can I use this outdoors?

A: The module itself is not weatherproof. It should be housed in an IP-rated enclosure for outdoor use.

Q: Does it require external calibration?

A: No, it comes pre-calibrated. However, sensitivity can be adjusted via serial commands if needed.

Q: What is the beam angle of the antenna?

A: The onboard antenna typically provides a wide detection angle of approximately 120 degrees.
