mmWave Human Presence Sensor with RS-485, LoRa, LoRaWAN Communication

A mmWave human presence sensor is a 60GHz FMCW radar device that detects human presence, motion, and micro-movements such as breathing within a room. The SUCH sensor covers up to 20m² with adjustable detection range and up to four zones, responds within 1 second, and supports RS-485 (Modbus-RTU), LoRa, and LoRaWAN communication. It is suitable for smart lighting, occupancy monitoring, and building energy management applications requiring accurate, non-intrusive presence detection.

Note: This presence sensor detects human movement, micro-movement, and stillness.

Feature

• 60GHz FMCW Radar: Detects both movement and stationary presence via Doppler and phase-change analysis, including subtle motion like breathing.
• 20m² Adjustable Coverage, ±60° Beam: Flexible zone setup for different room sizes and layouts.
• RS-485, LoRa, LoRaWAN Output: Supports Modbus-RTU and wireless protocols for direct integration into automation systems.
• Sub-1-Second Response: Detects presence in under 1 second, reverts to "no one" in about 30 seconds.
• Through-Obstacle Sensing: Penetrates thin materials like glass or wood for concealed installation.
• Impact-Resistant ABS Housing: Supports ceiling or wall mounting for continuous indoor use.
