The CTL-SEN-R7/3610 is a high-precision dual-tech presence sensor designed for the Tuya Smart ecosystem. Combining 24GHz FMCW mmWave radar with PIR technology, its cross-validation and self-learning capabilities detect subtle micro-motions (like breathing) while eliminating false alarms from airflows and thermal changes. With TY-Zigbee support, wide-range AC 100–240V power, and a built-in 0–32,000 Lux daylight sensor, it provides a stable, low-latency sensing solution for smart building automation.

Featuring advanced spatial coverage at a standard mounting height of 3.0 meters, this dual-tech presence sensor offers a micro-motion/stationary detection coverage diameter of approximately 6.0 meters and a major-motion detection coverage diameter of up to 8.0 meters.
The flush-mounted sensor has an outer diameter of 60 mm, a depth of 65 mm, and fits standard Φ50 mm ceiling cutouts.
Interference Mitigation: Keep away from moving objects (curtains, fans, plants), reflective metal/glass surfaces, HVAC air vents, and EMI sources. Adjust detection range to prevent false triggers through thin partitions.
Device Spacing: Maintain at least 4 meters between sensors; avoid pointing radar faces directly at each other to prevent co-channel interference.
Mounting & Handling: Mount on a solid, vibration-free surface and avoid flimsy, vibrating panels. Handle with care without pressing on the Fresnel lens or internal antenna.
Electrical Safety: Powered by AC 100–240V. Turn off mains power before wiring; must be installed by a qualified electrician. Use flame-retardant wiring without exposed cores, and ensure upstream circuits include leakage and overload protection.
Packaging Disposal: Recycle packaging per local environmental regulations. Keep plastic bags away from children to avoid suffocation hazards.
Disclaimer: Specifications are subject to change without notice. The manufacturer is not liable for device damage or losses caused by improper wiring, mounting, or uncalibrated conditions.
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.
