The Development of the Algorithm for Calibration and Temperaturehumidity Compensation of the Gas Sensor Readout on the Basis of the Stannic Oxide 000_14.pdf

The distinctive features of sensors on the basis the stannic oxide are high sensitivity, simple structure and the relatively low price. The main disadvantage of the sensors is the poor selectivity. Within the research, the gas sensor on the basis of the stannic oxide as a typical representative of the adsorption type sensors is chosen. The article discusses the calibration and improvement in the accuracy of gas sensors on the basis of the stannic oxide that are widely used in systems designated for the gaseous atmosphere composition control. The algorithms for calibration and temperature-humidity compensation of the gas sensor readout are developed. The algorithms allow to calibrate these sensors without using the complex equipment as well as to correct their readout depending on the temperature and humidity of the environment. The developed algorithms increase the readout accuracy of the sensor on the basis the stannic oxide. The proposed solutions are based on well-known approaches to sensor calibration and correction. The solutions also concretize the results relating to the MQ-13type of sensor.
