24GHz Radar Presence Sensor Switch

Add presence-based switching to a compatible lighting or control circuit with a 24 GHz radar sensor. Adjustable sensitivity, delay and light-sensing settings let the installer tune the response to the room.

• ✅ Respond to smaller movements - radar presence sensing can keep the circuit active beyond a simple walking-motion trigger.
• ✅ Tune the response - sensitivity and delay settings help adapt operation to the installation.
• ✅ Use ambient-light control where appropriate - the listed photosensor option can be enabled or disabled.

Tune Presence Detection to the Actual Room

Choose the mounting position with the detection area in mind, then test the response after installation. Fans, moving curtains and reflective surroundings can affect radar detection, so sensible placement matters as much as the settings.

This is a hardwired mains switch, not a Wi-Fi sensor. Have a qualified installer verify the actual unit's supply rating, load type and wiring before fitting; the selected listing is marked 100-240 VAC. Match any switched load to the unit's verified rating.
