The CTL-SEN-R7/3620 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-WiFi 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.
Features
Supports standard Tuya WiFi protocol for fast networking, stable connection, and seamless Tuya ecosystem integration.
24GHz FMCW radar and PIR cross-verification minimizes false alarms.
Captures subtle breathing; accurately detects major motion, micro-motion, and stationary presence.
Adapts intelligently to complex spaces for quick, simple commissioning.
Sensitivity and detection range can be adjusted independently.
Allows easy parameter configuration and status readback via remote.
Indicator brightness automatically adjusts to ambient lighting.

Mounting
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.
