Abstract
A cartridge-like chemical sensor is formed by a housing having a base and a cover fixed to the base and provided with an input opening, an output hole and a channel for a gas to be analyzed. The channel extends in the cover between the input opening and the output hole and faces a printed circuit board carrying an integrated circuit having a sensitive region open toward the channel and of a material capable to bind with target chemicals in the gas to be analyzed. A fan is arranged in the housing, downstream of the integrated device, for sucking the gas after being analyzed, and is part of a thermal control system for the integrated circuit.
