Abstract

The electronic plug-and-play electronic unit for controlling the semiconductor and thermocatalytic sensors is described. This is a controller with standard UART interface, which maintain preset working temperature of the sensor, measures resistance of the sensing layer, makes linearization of the sensitivity curve, compensates ambient humidity. In the case of thermocatalytic sensor, it measures power necessary to heat sensing and reference elements of the sensor, and the difference in these two values of power is proportional to the gas concentration. The digital output signal contains information about gas concentration, working parameters of the sensor, sensor type, enabling plug-and-play operation mode.
