Zigbee Presence Sensor with mmWave Radar & PIR, Battery Powered

The SUCH zigbee presence sensor is a zigbee 3.0 mmWave presence sensor that combines 24GHz mmWave radar with PIR detection to detect both moving and stationary human presence within a 5m range and 120° detection angle. Powered by 2×AAA batteries (up to 240 days) or USB Type-C, it supports flexible wireless installation and connects to a Zigbee gateway for remote monitoring, app notifications, and smart automation control. Compared with PIR-only sensors, its dual-sensor design provides more reliable human presence detection, especially when occupants remain still for extended periods — offering room-level occupancy monitoring for a wide range of smart home scenarios. Typical applications include smart lighting control, energy-saving automation, HVAC control, elderly care monitoring, baby safety monitoring, and home security systems.

Note: Detects both moving and stationary presence, even when occupants remain still.

Feature

• 24GHz mmWave Radar + PIR Dual Detection — Combines motion sensing with stationary presence detection, reducing missed detections that commonly occur with PIR-only sensors.
• Zigbee 3.0 Connectivity — Integrates with Zigbee-enabled smart home hubs and platforms for stable mesh networking and broad compatibility.
• 5m Detection Range with 120° Wide Angle — Covers standard room-sized areas for consistent whole-room presence coverage.
• Adjustable Sensitivity (0–10) — Lets users fine-tune detection levels to match different room sizes and use cases.
• Built-in Ambient Light Sensor (0–3500 LUX) — Enables automatic lighting control based on ambient brightness conditions.
• Temperature & Humidity Monitoring — 4-in-1 Version — Adds environmental data for automation triggers such as HVAC or ventilation control.
• Dual Power Options: AAA Battery or USB Type-C — Supports flexible, wire-free setup with up to 240 days of battery life, or continuous power via USB Type-C where wiring is available.
• Compact Wall-Mounted Design (72×25×20mm) — Enables easy installation in residential and commercial interiors.
