    Overview

    The SUCH microwave motion sensor is a 5.8GHz radar-based sensor engineered to detect both movement and micro-motion (such as breathing-level presence) that traditional PIR sensors often miss. With a detection range of up to 10 meters, an input voltage of DC9–24V, and dual NPN/Logic-Level output options, it integrates directly into a wide range of control systems without additional signal conversion. The sensor penetrates non-metallic materials such as glass, plastic, acrylic, and wood, allowing for concealed installation behind panels or enclosures. It is commonly used in occupancy-based lighting control, smart home automation, security systems, and AIoT-enabled devices requiring reliable human presence detection.

    Feature

    • 5.8GHz Microwave Radar Detection — Identifies both gross motion and micro-motion (e.g., a stationary person breathing), overcoming the limitations of infrared-based sensors that require visible movement to trigger.
    • Detection Range up to 10 Meters — Sensitivity is adjustable across four gears (2m / 5m / 7.5m / 10m default factory setting: 5m), allowing the detection zone to be tuned to room size or application requirements.
    • Dual Output Options: NPN / Logic-Level (High-Low) — NPN output directly drives loads up to 300mA (relays, indicators); Logic-Level output provides a clean high/low signal compatible with MCU and PLC digital inputs, simplifying integration with existing control panels.
    • Non-Metallic Material Penetration — Detects through glass, plastic, ceramic, acrylic, rubber, and wood, enabling installation inside enclosures or behind panels for a cleaner, tamper-resistant mounting solution.
    • Stable Performance in Variable Conditions — Detection accuracy is unaffected by ambient temperature, humidity, brightness, or lighting changes, and resists interference from dust or surface dirt — suited for both indoor residential and light industrial environments.
    • IP67-Rated, Wide Temperature Range — Operates reliably from -10°C to 60°C with IP67 ingress protection, supporting installation in bathrooms, entryways, and other moisture-prone areas.
    • Low Power Consumption — Draws less than 0.75W at DC9–24V (±5%), making it suitable for battery-backed or always-on lighting and security systems.
    • Fast Response, Configurable Delay — Response time under 1500ms, with an adjustable target-leave delay (2s default, 10–60s customizable), reducing false triggers in high-traffic detection zones.

    FAQ

    It emits low-power 5.8GHz microwave signals and analyzes the reflected waves; any change in the return pattern, including subtle micro-motion, triggers detection.

    Yes, it operates with low-power microwave signals well below levels associated with heating or high-energy radiation, making it safe for continuous residential and commercial use.

    It can penetrate non-metallic materials such as glass, plastic, acrylic, and wood, but detection does not pass through cement walls thicker than 15cm.
