Desk & Seat Occupancy Sensor
The Hot Desking, Make It Cool
The Hot Desking, Make It Cool
The sensor's impressive desk & seat occupancy detection capability frees up human resources enabling efficient management.
Based on the highly sensitive PIR, VS340 is designed
for high-cost performance, which meets general
needs.
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.
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.
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.
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.
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.
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.
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.
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.
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.

Desk occupancy sensors can be very helpful in modern offices, especially with hybrid work models. They provide real-time data on desk usage for facility managers to optimize office layouts, reduce real estate costs, and streamline hot desking. By integrating with building systems to control lighting and HVAC, these sensors also support energy efficiency and operational cost savings. They improve the employee experience by ensuring workspace availability and triggering cleaning alerts for healthier environments.
Desk occupancy sensors use advanced technologies like Passive Infrared (PIR) and thermopile to accurately detect workstation usage. For example, Milesight VS34x series desk occupancy sensors employ PIR for motion detection and Thermopile IR for temperature variation, offering up to 98% accuracy. These sensors feature adjustable detection angles, real-time monitoring (within 13 seconds for occupancy), and wireless communication via LoRaWAN® and Milesight D2D protocols.
Desk occupancy sensors are highly suitable for flexible or shared office spaces. They provide real-time data on desk usage for space optimization, helping to reduce workspace needs and real estate costs. For hot desking, these sensors facilitate automatic desk booking and release to maximize resource utilization. They also enhance the employee experience by reducing time spent searching for workspaces. The data-driven insights gathered inform decisions about office layout and resource allocation. Additionally, these sensors can integrate with other building systems to optimize energy use.
Many desk occupancy sensors are designed with strong privacy protections. For example, the Milesight VS34x series features anonymous detection that monitors occupancy without capturing personally identifiable information or images, ensuring compliance with privacy regulations like GDPR. They rely on non-invasive technology, avoiding cameras and instead detecting heat and movement. The sensors only collect basic occupancy and usage data, which is transmitted through the LoRaWAN® network. Organizations can ensure transparency and foster acceptance by clearly communicating how data is collected and used.
Investing in desk occupancy sensors offers strong ROI for organizations, especially in hybrid workplaces. They help eliminate ghost bookings, improve space utilization, and reduce real estate costs. Automation of desk and meeting room bookings boosts operational efficiency, while targeted cleaning reduces maintenance costs. Energy consumption drops with smart control of lighting and HVAC. Data insights guide better decision-making, improve space planning, and support sustainability goals.
