Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

The landscape of smart sensors in 2026 presents a complex but rewarding challenge for those looking to enhance their home automation setups. With options ranging from PIR motion sensors to mmWave ...
