Presence and light radar sensor OXT T150 230V Wi‑Fi (Tuya) for occupancy and brightness detection

OXT T150 is a 230V radar presence and light sensor with Wi‑Fi connectivity and Tuya compatibility, designed for indoor occupancy and ambient light detection. The device combines microwave radar technology for motion sensing with a built‑in light meter to enable automatic switching of luminaires and integration into smart home or building automation systems. Its 230V direct supply and wireless control via Tuya allow straightforward retrofit into existing lighting circuits without additional gateway hardware for many setups.

Advantages

The sensor provides reliable motion detection using radar technology, which performs well through thin obstructions and is less affected by temperature changes than passive infrared sensors. Integrated ambient light measurement prevents unnecessary switching by evaluating current brightness levels before activating lighting. Wi‑Fi connectivity and Tuya compatibility enable remote configuration, scene creation and integration with voice assistants or mobile control apps. The compact design and 230V direct connection simplify installation in standard electrical boxes and reduce the need for extra power modules.

Suitable for

• Office rooms and open-plan workspaces for automatic lighting control
• Corridors and stairwells to ensure lights operate only when needed
• Bathrooms and utility rooms where occupancy-based activation improves convenience
• Residential rooms and hallways for energy-saving presence-triggered lighting

How to use

Install the OXT T150 in a suitable indoor location where it has an unobstructed view of the monitored area and can accurately assess ambient light. Connect the device to a 230 V AC supply following local electrical codes and the manufacturer’s wiring diagram. Pair the sensor with the Tuya app over Wi‑Fi to adjust sensitivity, hold time, and lux threshold values. Configure scenes or schedules in the app to tailor automatic switching behavior according to occupancy and daylight levels.

Usage recommendations

Position the sensor so its field of view covers the typical movement paths while avoiding direct exposure to large heat sources or reflective surfaces that could affect radar performance. Set the lux threshold to match desired lighting conditions for the space and fine‑tune sensitivity to reduce false triggers in high‑traffic areas.
