About this product

The Desk & Seat Occupancy Sensor VS340 is designed for general needs with highly sensitive PIR detection.
The Desk & Seat Occupancy Sensor VS341 is designed for specific applications with dual-technology PIR thermopile detection for higher accuracy.
Both sensors can be deployed wirelessly using LoRaWAN technology, providing low power consumption, long-distance transmission, and anonymous detection.
The sensors have adjustable detection angles and offer a 98% accuracy rate.
They have a long service life of 5 years and can be easily installed with peel-and-stick mounting.
The sensors can be configured wirelessly using NFC and have additional features such as energy-saving control and fast response times.
