VS340 Desk and Chair Occupancy Sensor (Hot Desk)
Based on a highly sensitive PIR sensor, the VS340 is designed
for high performance that meets general needs.


Wireless LoRaWAN Deployment
Easy and convenient wireless deployment eliminates network connection issues. The advantages of LoRa technology ensure low power consumption, long-range transmission, deep penetration, and anonymous detection.
Dual PIR and Thermopile Technology
The VS341 utilizes both highly sensitive PIR sensors and thermopiles for accurate presence detection. The dual detection mechanism fully captures movements and temperature changes in target areas, contributing to reliable results.


98% Industry-Leading Accuracy
Based on dual technology, the sensor can achieve up to 98% high accuracy. It meets general requirements and enables precise detection, outperforming most similar products.
Fast Response with Low Latency
The sensor can quickly process data to detect occupancy status within 13 seconds and vacancy within 60 seconds, ensuring near real-time performance. This is valuable for efficiency-driven applications to enable quick responses and timely actions.


Adjustable Detection Angles
Target areas can be adjusted according to needs. To avoid unnecessary detection and focus on specific areas, the sensor is equipped with 5 different covers, making it preferable for detecting various desk and table occupancy scenarios with different coverage ranges.
5-Year Long Battery Life
Based on LoRaWAN’s low power consumption, the sensor can maintain a long battery life of 5 years with frequent reporting. This makes it an ideal solution for meeting most user requirements in various applications.


Smart Energy-Saving Control
Milesight’s exclusive LoRa protocol allows the sensor to communicate easily with other Milesight LoRaWAN devices without a gateway within 1 second. It can also detect occupancy status to control the DS3604 E-link IoT Display, providing a convenient workstation availability indicator.
Easy and Quick Installation
The thin and lightweight design, along with a "peel-and-stick" mounting system, makes it convenient for mass deployment. It can be used in any application, even in large quantities. Minimal effort is required, and the setup can be done easily.
