Functions


This radar detects whether the user wants to use the shower room based on the user's displacement direction and movement speed within its signal coverage area, thus opening the shower room door in advance and closing the door automatically after the user enters/leaves the shower room.



Features



Support for ground concealed installation.

High resistance to interference.

With micro-motion detection.

Size of only 12*60.5mm, which can be adapted to a variety of structures.

Achieve accurate judgment while filtering invalid behaviors based on FM continuous wave radar technology and uniquel energy accumulation algorithm.

Unaffected by temperature, humidity, noise, airflow, dust, Light, etc., suitable for harsh environments

Low output power, no harm to human body


Applications

Shower rooms

Whole house control

The antenna of this radar can reach 120 degrees of horizontal/vertical sensing range and can be installed concealed on the ground. The 24GHz radar can achieve micro-motion detection and high-precision range monitoring, enabling accurate judgment within a controlled distance.
