Yeastar Workplace
People Counting Sensor
People Counting Sensor
The People Counting Sensor, based on Artificial
Intelligence (AI) technology, detects presence and
monitors meeting room occupancy in real time
in the modern workspace.
With a detection area up to 48 m² (installed on the
celling) and a 95% recognition rate, fewer sensors
are needed, cutting the deployment costs for
companies and organizations.
If a room is booked and yet no one shows up, the
Sensor will automatically free it up. Then, the
room status will be synced and updated on Yeastar
Meeting Room Booking System and Yeastar Room
Display, helping organizations eliminate ghost
meetings and increase space utilization.
Most importantly, only counter values will be
transmitted over the LoRaWAN® network, which
significantly reduces privacy concerns.
- AI-powered, with accuracy rate of 95%
- Wider detection range (up to 48 m² with 12 mapped
regions), and better yet, customize the detection
regions according to the layout of your meeting
rooms - No facial recognition is involved in the detection
process, and no image data is collected, free from
privacy concerns
- Constantly detects presence and transmits
headcount to Yeastar Room Display and Yeastar
Meeting Room Booking System via LoRaWAN®
Gateway - Auto-releases rooms from ghost meetings and
syncs the room status with Yeastar Meeting Room
Booking System, increasing space utilization rate - Equipped with Wi-Fi for Web GUI configuration
