Bfly Smart Human Presence Detector
Upgrade your home automation system with the Bfly Smart Human Presence Detector, an advanced millimeter-wave (mmWave) radar sensor designed to detect human presence, even when a person remains still. Unlike traditional motion sensors that may stop detecting someone who is sitting quietly, this sensor can detect subtle movements, including breathing and micro-movements, depending on the installation environment.
Featuring a built-in illuminance sensor, adjustable detection capabilities, and support for smart home automation platforms, it is ideal for automatically controlling lights and other compatible devices based on room occupancy and ambient brightness.
Its compact recessed design makes it suitable for installation in ceilings and other compatible locations.
Key Features
Advanced mmWave Radar: Detects human presence, including subtle movements and breathing-related motion.
Stationary Presence Detection: Detection range up to 6 meters, according to the product label.
Moving Detection: Detection range up to 10 meters, according to the product label.
Built-in Light Sensor: Measures ambient brightness from 0 to 3,000 lux.
Intelligent Lighting Automation: Enables lighting control based on occupancy and brightness when configured with compatible devices.
WiFi / Zigbee Options: Available in different protocol versions; confirm the specific model before ordering.
Smart Home Integration: Supports Home Assistant and Zigbee2MQTT compatibility as indicated on the packaging, subject to the selected version and configuration.
Recessed Installation: Requires a mounting opening of approximately 51–57 mm.
Wide Voltage Input: AC 80–250V, as specified on the product packaging.
