Tronic Real Presence Sensor, 3 m Detection with Motion and Breathing Sensing

Our review

This Tronic sensor is a presence detector rather than a plain motion switch. Its 3-metre detection range covers a desk, doorway or small room, and it works by picking up both movement and the faint breathing of someone sitting still, so lights are less likely to switch off while a person is quietly reading or working. It suits anyone automating a room where people stay put, such as a home office, study or bathroom. Before buying, confirm the 3-metre range reaches where people actually sit, and check how it will be wired or mounted, since no specifications are listed. Compared with ordinary PIR motion sensors, which often cut out when you stop moving, this one aims to hold presence longer; against a basic occupancy switch, it adds the breathing-sensing approach.
