VS341 - PIR & Thermopile Presence Detection Sensor with LoRaWAN® and Advanced Features
Dual-technology presence detection with PIR and Thermopile, transmission via LoRaWAN®, and remote management for precise space monitoring
General Description
The VS341 is a presence detection sensor that combines PIR (Passive Infrared) and Thermopile technologies to provide exceptional accuracy in space monitoring. This sensor is designed to detect presence in environments such as offices , coworking spaces , retail stores , and conference rooms , with an accuracy of up to 98% recognition rate.
The sensor uses LoRaWAN® for data transmission, enabling remote information management in IoT networks. It is particularly suitable for space management applications in connected buildings and smart building solutions. Powered by a 4000 mAh Li-SOCl2 battery, it offers a battery life of up to 5 years with a typical daily use of 100 triggers.
With an IP30 protection rating, the sensor is designed for indoor use, while offering great installation flexibility thanks to fixing with 3M tapes or screws. It is designed to operate in temperatures ranging from -20°C to +60°C , making it suitable for a wide range of environments.
Targeted Applications
- Presence monitoring in shared offices , coworking spaces , meeting rooms , and stores
- Intelligent management of connected buildings and public spaces
