New and Underutilized Technology: Vending Machine Occupancy Sensors

The following information outlines key deployment considerations for vending machine occupancy sensors within the Federal sector.


Vending machine occupancy sensors detect when no people are in the vicinity and powers down beverage vending machines. These systems do not completely turn off compressor, but reduce their run times.


Vending machine occupancy sensors are applicable in most building categories where vending machines are present.

Key Factors for Deployment

Occupancy sensors or similar features should be an integral part of new vending machine purchases.
