Beschreibung
Zusammenfassung:	A sensor with a built in calibration gas source having an outer housing configured to contain one or more of the sensor elements. Within the housing is a controller configured to manage operation of the sensor and a user interface configured with one or more user input elements and one or more sensor output elements. A detector module has one or more detectors, configured to sense a calibration gas and, responsive to detection of the calibration gas, provide a detection signal to the controller. A calibration module configured to, responsive to a control signal from the controller, generate a calibration gas and present the calibration gas in proximity to one or more of the detectors. A power source is also provided and configured to provide power to the controller, the detector module, and the calibration module.
