📡 24GHz mmWave Human Presence Sensor (Respiratory Motion Detection)
🔹 Brief Introduction
The 24GHz mmWave Human Presence Sensor is an advanced radar-based occupancy detection device designed for high-precision smart home automation. Unlike traditional PIR motion sensors, it detects not only movement but also subtle human activities such as breathing and micro-motion.
This makes it ideal for environments where continuous presence detection is required, such as bedrooms, offices, meeting rooms, bathrooms, and energy-efficient smart buildings. It ensures accurate occupancy detection even when a person is completely still.
⚡ Features & Benefits
🔍 High-Precision Human Presence Detection
Uses 24GHz mmWave radar technology to detect both movement and stationary presence, including respiratory micro-motion.
🏠 Smart Home Integration Ready
Designed for seamless integration with smart home systems, enabling automation for lighting, HVAC, security, and energy-saving scenarios.
🔌 Dry Contact Output Support
Provides flexible relay signal output (dry contact), allowing compatibility with a wide range of controllers and automation systems.
🌙 Detects Stationary & Sleeping Humans
Unlike PIR sensors, it can accurately detect people even when they are not moving, improving reliability in real-world smart home applications.
⚡ Energy Efficiency & Automation Optimization
Helps reduce unnecessary power consumption by ensuring systems like lights and air conditioning operate only when presence is detected.
📡 Stable & Low False Trigger Performance
Less affected by temperature, light, or environmental noise compared to infrared-based motion sensors.
