Desk & Seat Occupancy Sensor VS340

Based on the highly sensitive PIR, VS340 is designed
for high-cost performance, which meets general
needs.

Desk & Seat Occupancy Sensor VS341

Based on the dual-technology of PIR and thermopile, VS341 is
designed for bringing higher accuracy and quick occupancy
status detecting for more specific applications.

LoRaWAN® Wireless
Deployment

Easy and convenient wireless deployment dispenses with being perplexed by network connection. The benefits of LoRa technologies guarantee low power consumption, long-distance transmission, deep penetration, and anonymous detection.

Dual-Technology of PIR
& Thermopile

VS341 employs both highly sensitive PIR and thermopile sensors to accurately detect occupancy. The double detection mechanism fully captures the motions and temperature variations in its target areas and contributes to trustworthy results.

98% Industry Leading
Accuracy

Based on dual technology, the sensor is capable of reaching an up to 98% high accuracy. It satisfies general requirements and further makes accurate detection possible, beating the most similar products.

quick occupancy status response

Timely Response with Low Latency

The sensor can process rapidly to detect the status of occupied reaching 13s and not occupied reaching 60s, bringing near real-time performance. It is valuable for effectiveness-oriented applications to gain fast responses and take timely actions.

Adjustable Detection
Angles

The target areas can be varied as appropriate. To avoid unnecessary detection and focus on the aim regions, the sensor is equipped with 5 different covers, making it preferable for detecting different table and desk occupancy with various ranges in different scenarios.

long battery life

5 Years Long Service Life

Based on the low power consumption LoRaWAN®, the sensor can maintain a long battery life of 5 years with a frequent report rate. It is ideal for covering most user demands in different applications.

Energy-Saving Smart
Control

The exclusive Milesight LoRa®-based protocol allows the sensor to easily communicate with other Milesight LoRaWAN® devices without a gateway within 1 second. It can also detect occupancy status to control the DS3604 E-ink IoT Display, providing a convenient indication of workstation availability.

fast and easy deployment

Easy and Fast Deployment

The thin-and-light design and peel-and-stick mounting make it convenient for bulk deployment. It can be applied in any application with even a large amount. Not much energy is needed and the deployment can be easily done.
