Netvox’s R311WA wireless seat sensor utilises LoRaWAN® to detect seat occupancy. This smart sensor monitors pressure to assess whether a seat is in use. For optimal discretion, the sensor can be placed under seat cushions to maintain the overall aesthetics of your premises.

This LoRa occupancy sensor can be added to your existing occupancy monitoring solution. The R311WA seat sensor provides an excellent solution for Smart Cinemas, Theatres and Stadiums.

Using the LoRaWAN® protocol, the LoRa occupancy sensor wirelessly monitors occupancy through a centralised monitoring system. With the ability to set pre-configured alerts to your preferred platform and devices, this LoRa occupancy sensor offers a flexible two-way solution.

Compatible with all leading third-party platforms, the Netvox seat occupancy sensor can be quickly set up for simple visualisation and analysis.
