The CTL-SEN-R5/2103 is a high-precision human presence sensor powered by advanced 24GHz FMCW millimeter-wave radar technology. Featuring a versatile 0 to 60° adjustable detection angle, it allows for flexible positioning to target specific areas and minimize blind spots. By detecting micro-motions (such as breathing), the sensor accurately identifies both moving and stationary occupants. With a detection range of up to 8.0 meters and an integrated high-precision illuminance sensor (0 to 32,000 Lux), it is engineered to deliver optimal energy efficiency and automation for smart homes, commercial offices, and healthcare facilities.

Supporting flexible angle adjustments from 0° to 30° and 60°, this adjustable 24 GHz millimeter-wave radar breathing-presence sensor delivers tailored coverage patterns at a standard mounting height of 3.0 meters:
0° vertical mounting: Delivers a symmetrical circular coverage with a horizontal detection diameter of approximately 2.0 meters.
30° angled mounting: Delivers a directional fan-shaped coverage, achieving a maximum forward detection distance of up to 4.8 meters (with a backward range of approximately 0.2 meters), a maximum overall transverse span of approximately 5.0 meters, and a longitudinal span of approximately 3.6 meters.
60° angled mounting: Delivers a wide-range directional coverage, achieving a maximum forward detection distance of up to 8.0 meters, with both maximum transverse and longitudinal spans of approximately 8.0 meters.
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.
