The CTL-SEN-R5/2581 is a high-precision human presence sensor powered by advanced 24GHz mmWave radar technology and proprietary signal processing algorithms, enabling it to detect micro-motion (such as breathing) for stationary presence detection while effectively filtering non-human interference. With a detection range of up to 10 meters and an integrated high-precision illuminance sensor (0 to 32,000 Lux), it is engineered for advanced smart building applications; furthermore, it features a dedicated internal slot and interface for a User-defined Module Board, allowing customers to integrate bespoke communication or functional modules for highly tailored applications.

Interference Avoidance: Avoid installing near constantly moving objects (e.g., curtains, plants) or large reflective surfaces (e.g., metal ducts, mirrors) to prevent false triggering.
Device Spacing: Maintain a minimum distance of 4 meters between multiple sensors to prevent mutual interference.
Mounting: Ensure the installation surface is vibration-free. Note that radar signals can penetrate surfaces; avoid moving objects directly behind the installation wall/ceiling.
Wiring Safety: Disconnect power before wiring. Use certified cables and ensure the circuit includes appropriate short-circuit and overload protection.
Disclaimer: Specifications are subject to change without notice. Please follow all wiring diagrams strictly. The manufacturer is not liable for issues caused by improper installation.
Designed for ultimate convenience and efficiency, this product supports quick on-site configuration and parameter reading using an infrared (IR) remote control. Once deployed, debugging and maintenance can be easily accomplished even without relying on a smart home platform.
