offering superior precision compared to classic PIR sensors. Detects micro-movements within a distance of 0.75 m to 5 m,

with a coverage angle of: ±60° in the upper area and 360° in the lateral area. The sensor uses radar technology

24GHz mmWave , much more advanced than classic 5.8GHz sensors. Ideal for monitoring environments

such as bedrooms, bathrooms , offices , hotels or common areas, where the user may remain immobile for long periods.

Compatible Apps: Tuya Smart and Smart Life

You can manage all the features via the free Tuya Smart or Smart Life apps, available for Android and iOS.

View sensor status in real time , set custom delays (e.g. turn off after X seconds) and

Create smart scenes integrated with other Tuya devices, such as lights , sockets , sirens o Thermostats . You can adjust the sensitivity

three-level detection : High, Medium or Low , to adapt the sensor's behavior to the environment.

Voice Control and Assistant Integration

The sensor is compatible with Amazon Alexa and Google Home , allowing you to manage connected smart devices

even via voice commands . You can activate or deactivate scenarios, receive voice notifications in real time when

a presence is detected (e.g. “Motion detected in the living room”) and integrate the sensor into customized routines .

Smart Automations and Custom Scenes

Thanks to the full integration with the Tuya Smart app, you can create intelligent automations and customized scenarios that

are activated based on the presence or absence detected by the sensor. You can, for example, turn on automatically

lights when it detects someone entering a room, or turns off a radiator if it detects that the room is

empty for a certain period. You can activate a camera or an alarm in case of night detection,

or manage the lighting in the bathrooms or corridors, turning it on only when needed and turning it off afterwards

the exit to avoid unnecessary energy waste. Each automation can be customized with timers ,

different conditions and devices, to offer you a truly tailor-made smart experience.
