Microwave Sensor for Human Detection, 4-16m, 10A/30A

The SUCH microwave sensor for human detection identifies presence by sensing subtle changes in object displacement, offering advantages over traditional PIR sensing methods and remaining unaffected by ambient temperature. Operating at 5.8GHz, it penetrates non-metallic materials such as drywall, glass, and plastic, with a detection range of 4–16m and an adjustable angle of 30°–170°, suiting both ceiling and wall installation. A reverse output version is also available, keeping the circuit closed normally and disconnecting the load after human detection — suited for UV sterilization lamp control and unattended-kitchen shutoff applications.

Feature

• 5.8GHz microwave detection (<1mW output): Detects human presence through drywall, glass, and plastic panels, offering advantages over traditional PIR sensing methods, with stable performance unaffected by ambient temperature.
• 4–16m detection range, 4-level adjustable: Covers small rooms up to large open areas; range decreases when sensing through thicker barriers such as walls or glass.
• 30°–170° angle adjustment: Supports ceiling mounting at 3–5m or wall mounting at around 1.5m, adapting to different installation environments.
• Two load options — 10A (≤800W) and 30A (≤1500W): Matched to different load types, including incandescent, LED, exhaust fans, and energy-saving lamps, each with its own recommended wattage limit.
• Standby power approx. 0.6W: Supports continuous operation with minimal power draw.
• Reverse output mode available: Circuit remains closed normally and disconnects the load after human detection, suited for applications such as UV sterilization lamp control and unattended-kitchen fire safety shutoff.
• 1–3 minute self-check after power-on: Allows the sensor to stabilize before use; installation should avoid continuously moving objects (e.g., fans) and high-power electromagnetic equipment (e.g., radios, walkie-talkies).
• 110–220VAC, 50Hz input: Compatible with standard commercial and residential electrical systems; indoor installation only.

Wiring

Tips: For low-power loads such as single LED lamps or small electrical devices. The microwave sensor directly controls the load without an additional contactor.

Tips: For high-power loads or multiple lamps. The microwave sensor controls the AC contactor, which switches the main power circuit to protect the sensor relay from overload.

Detection (Unit:m)

Tips: The detection sensitivity of the microwave sensor for human detection is affected by installation height. A ceiling mounting height of 3–4m above the ground is recommended for optimal detection performance.
