MILESIGHT - PIR & ToF occupancy sensor for LoRaWan sanitary units

VS330-868M presentation

The Milesight VS330 is an intelligent occupancy sensor designed to monitor the occupancy status of cabins, washrooms or confined spaces in real time. It combines two detection technologies.

PIR (passive infrared detection): detects movement based on body heat.

ToF (Time of Flight): measures distance by calculating the time it takes a wave to travel back and forth between the sensor and an object.

This dual technology enables precise detection, even in the absence of movement, ensuring accuracy in excess of 99.5%. The sensor is RGPD-compliant, guaranteeing 100% anonymous detection without the collection of personal information.

The VS330 is powered by three 4000 mAh ER18505 batteries, offering a battery life of around 4 years. Its compact PC+ABS (fire-retardant) housing is designed for wall or ceiling installation, with an adjustable detection angle from 0° to 75°. It features a moisture-resistant coating, making it suitable for environments such as bathrooms.

VS330-868M applications

• Monitor occupancy of toilet cubicles in public places.
• Manage the use of fitting rooms or private areas in retail outlets.
• Optimize the use of shared workspaces or meeting rooms.
• Automatically trigger lighting or ventilation systems according to occupancy.
• Collect data to analyze facility use and plan cleaning services.

VS330-868M functions

• Occupancy detection: combination of PIR and ToF sensors for accurate detection.
• Real-time update: updates occupancy status every 5 seconds.
• Ultra-low energy consumption: extended autonomy with a single set of batteries.
• RGPD compliance: anonymous detection without personal data collection.
• Moisture-resistant design: conformal coating protects against moisture.
• Adjustable detection angle: set the detection angle from 0° to 75° to suit different environments.
• Configuration via NFC: easy set-up using a mobile app.
• LoRaWAN® compatibility: integration with standard LoRaWAN® gateways and network servers.
