Gas sensor, control method and storage medium

Abstract

The invention discloses a gas sensor, a control method and a storage medium. The gas sensor comprises a substrate, a gas sensitive device and a thermosensitive circuit. The gas sensitive device is arranged on the first surface of the substrate; and the thermosensitive circuit is arranged on the substrate and is used for heating the gas sensitive device when the working environment temperature of the gas sensitive device is lower than a preset temperature threshold value. According to the embodiment of the invention, the gas sensor is internally provided with the thermosensitive circuit, so that the gas sensitive device can be heated through the thermosensitive circuit when the working environment temperature of the gas sensitive device is relatively low, the working environment temperatureof the gas sensitive device is not relatively low, the measurement accuracy of the gas sensitive device is further ensured, and the wide-temperature working function of the gas sensor is realized.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a gas sensor, a control method and a storage medium. Background technique [0002] The semiconductor gas sensor is made of some metal oxide semiconductor materials, such as tin oxide, at a certain temperature, the electrical conductivity changes with the change of the ambient gas composition, and is widely used to detect a variety of harmful gases. A gas sensor based on TFT (ThinFilm Transistor, thin film transistor) is produced by combining the above theory with the circuit structure of the thin film transistor inside the liquid crystal display. [0003] However, when the gas sensor is working, it is greatly affected by the environment, especially in a low temperature environment, the measurement results fluctuate greatly, and accurate measurement cannot be achieved, resulting in poor measurement performance of the gas sensor in a low temperature environment.
