Multi-condition sensing device including an ir sensor

Abstract

Techniques are disclosed for using an infrared (IR) sensor to sense flame and/or activity within an environment of a building, such as a home or office. One example embodiment provides a multi-condition sensing device that includes an IR sensor for sensing both human occupancy and fire within a given environment. Another example embodiment provides a multi-condition sensing device that includes a plurality of sensors. A first of the sensors includes an IR sensor that is adapted to sense IR radiation within a given environment. A second of the sensors is adapted to sense a second environmental condition (different than IR radiation) within the given environment. Another example embodiment provides a standalone modular sensor block with a standard communication interface to a building management system. The sensor block may act as a combo-sensor as well as an active fire detector and alarm.
