mmWave Radar Presence Sensor, RS485 Output

Description

The mmWave Radar Presence Sensor uses sensitive radar technology to detect human presence through breathing, heart rate, and micro-movements. The smart presence sensor supports fall alerts, distance detection, and range setting, accurately sensing even stationary people up to 4 meters. RS-485 output enables smart data collection and management.

Specification

Feature

Applications

Tips: What is mmWave Radar Presence Sensor?

The mmWave Radar Presence Sensor is a high-precision sensor that utilizes millimeter-wave radar technology to detect human presence, movement, and micro-motion, even through non-metallic obstacles such as glass or plastic. Unlike traditional infrared or ultrasonic sensors, mmWave radar operates reliably in various lighting and environmental conditions, offering higher accuracy and privacy. It is ideal for applications such as smart lighting, security monitoring, and elderly care, providing real-time occupancy detection and status feedback with minimal false triggers.
