360° Infrared Motion Sensor Ceiling Indoor Surface Mount PIR Sensor Switch for LED Lights Programmable Time & Lux 6m Range Presence Sensor 2000W/1000W Load 3-Wire Installation (White)

Very easy to install and set up. Good value as well.

Fairly easy to install and has so far had good sensitivity. I fitted this ceiling PIR in a utility area and the wiring was straightforward for a 3-wire unit, with enough room inside for a tidy connection. The low-profile body sits neatly on the ceiling and does not stand out too much once in place. In day-to-day use, it picks up movement quickly and reliably across the space, and the 360 degree coverage is useful for awkward corners. I also like that you can adjust both the hold time and the light level threshold, so it only comes on when needed and does not trigger unnecessarily in bright conditions. For the price, it feels like a practical upgrade over a standard switch, especially in spots where lights are often left on by mistake. It has been dependable so far, and the combination of easy setup, good detection range, and adjustable settings makes it very handy.

I ordered this for my shed as i keep forgetting to turn the light off Installation is super simple and involves wiring the 'in' side junstion with the live and neutral wire from the mains and a live and neutral wire out to the load ( light in my case ) The sensor works really well and can be set for different ambient light levels and timer function so will stay on when set between 10 seconds to 10 mins Its low profile for surface mounting, the only thing i wish it had is side holes for wiring from the side as it only has holes for ceilling mounting . Over all this gets five stars and its easy to fit, low profile and had been performing really well thus far.
