Seat Occupancy Sensor

  • The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 – 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.

    Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements. Seat sensor features a stress plate and stress-sensitive ribbon. This monitoring solution alerts when it detects pressure. Use in venues, such as stadiums & theatres, to optimize operations with occupancy data.
