The µBright infrared sources, the latest of Cambridge CMOS Sensors’ gas sensor components for low-power, long life optical gas sensing solutions was launched at SENSOR+TEST in Nuremberg. Designed to operate across the wideband IR range (2 to 14µm) the µBright sensors can be used to continually sense gases, such as carbon dioxide, and ethanol vapours in NDIR (nondispersive infrared) systems at low power.
