TruePresence® Multisensor IP Recessed

Key Features

• True presence detection: Detects human presence through micro-movements and vital signs such as breathing, ensuring precise occupancy monitoring even when individuals are motionless.

• Multisensor technology: Integrates sensors for temperature, humidity, air pressure, volatile organic compounds (VOC), and ambient light to deliver complete environmental insight.

• IP network control: Supports REST and MQTT protocols for direct integration with IP-based building management and IoT systems, enabling real-time data communication.

• Seamless recessed design: Discreet ceiling-mounted design for aesthetic integration in modern office, education, and healthcare interiors.

Product Description

The Steinel True Presence Multisensor® IP Recessed is a precision-engineered solution for smart building environments, combining accurate presence detection with environmental sensing. Using advanced high-frequency radar technology, it identifies even the smallest human movements and vital signs such as breathing, ensuring true occupancy detection without false triggers. The multisensor array simultaneously measures temperature, humidity, air pressure, VOC, and ambient light, providing vital data for energy-efficient control and comfort optimisation.

Its recessed mounting design offers a sleek and unobtrusive appearance ideal for professional settings. With REST and MQTT connectivity, the sensor communicates directly over IP networks and integrates seamlessly with building automation and IoT platforms. Power over Ethernet (PoE) provides both data and power through a single cable, simplifying installation and reducing infrastructure costs.
