Product Description

The Milesight VS34x series includes advanced Desk & Seat Occupancy Sensors, specifically designed for optimizing workspace management. These sensors are ideal for various applications, including hot desking in offices, space utilization in libraries, dining areas, and traffic hubs. The series consists of two models, the VS340 and VS341, each catering to different levels of occupancy detection needs.

Desk & Seat Occupancy Sensor VS340

The VS340 model employs highly sensitive Passive Infrared (PIR) technology to detect occupancy. It is designed for high-cost performance and meets general requirements for occupancy sensing with up to 95% recognition rate. The VS340's PIR detection area covers 107° horizontally and vertically, with a detection distance within 1 meter.

Desk & Seat Occupancy Sensor VS341

The VS341 model incorporates dual technology, combining PIR and thermopile sensors, to achieve higher accuracy in occupancy detection, reaching up to 98%. This model is particularly effective for more specific applications requiring quick and accurate detection of occupancy status. The thermopile sensor has a detection area of 50° (at 50% level of sensitivity).

Key Features

  • LoRaWAN® Wireless Deployment: Easy and convenient wireless setup, leveraging the benefits of low power consumption, long-distance transmission, and deep penetration.
  • Dual-Technology: Combines PIR and thermopile sensors for accurate occupancy detection.
  • High Accuracy: Up to 98% accuracy with the dual-technology approach.
  • Timely Response with Low Latency: Quick detection of occupancy status, with a response time of 13 seconds for occupied and 60 seconds for not occupied.
  • Adjustable Detection Angles: Equipped with 5 different covers to focus on specific target areas in various scenarios.
  • Long Battery Life: Approximately 5 years with a frequent report rate, ideal for various applications.
  • Energy-Saving Smart Control: Utilizes the exclusive Milesight LoRa®-based protocol for efficient communication with other Milesight LoRaWAN® devices.
  • Easy and Fast Deployment: Features a thin-and-light design with peel-and-stick mounting for bulk deployment.

Typical Applications

  • Hot Desking: Efficient management of workspaces in offices.
  • Libraries: Optimizing space utilization.
  • Dining Areas: Managing occupancy in dining facilities.
  • Traffic Hubs: Monitoring and managing traffic flow in public areas.

Installation and Configuration

  • NFC Configuration: Enables wireless device configuration and management through the Milesight ToolBox app.
  • Installation Options: Offers flexibility with 3M tape mounting and wall screw mounting.

The Milesight VS34x series Desk & Seat Occupancy Sensors offer innovative solutions for efficient space management and utilization in various environments, combining advanced technology with user-friendly deployment​.
