Time dependences in the thermo-cyclic mode of the conductivity of CO sensors, constructed in a traditional four-electrode and a planar three-electrode design on the basis of thin nanocrystalline tin dioxide films, are analyzed. The analysis showed that the use of the Pt/Pd/SnO2:Sb sensors in a planar design in the thermocyclic mode with a long cooling cycle makes it possible to detect smoldering products at a significant reduction of power consumption.
