Abstract

A device (10) for automatically controlling an air maintenance system (12) is disclosed. The device uses a Passive Infra-Red (PIR) detector (14) to count the number of movements within an enclosed space during a specified time period. Readings from a temperature sensor (16) may also be included. A processor (18) then estimates the number of people within the enclosed space and thereby activates the air maintenance system (12) at a suitable activation level. Preferably, a PIR detector (14) with no latching-on period is provided. Communication between the processor (18) and the air maintenance system is preferably by way of a radio transceiver (32).
