Abstract

The invention relates to temperature compensation equipment and method. The temperature compensation equipment comprises a gas sensor; a thermosensitive element, wherein the first end of the thermosensitive element is grounded; a voltage dividing device, wherein one end of the voltage divider is connected with a power supply, and the other end is connected with the second end of the thermosensitive element; a single chip microcomputer respectively connected with the second end of the thermosensitive element and the gas sensor; wherein the single-chip microcomputer obtains a current temperature value according to the voltage value of the second end of the thermosensitive element and obtains a temperature compensation value according to a preset corresponding relation. The accuracy of an output signal of the gas sensor is easily influenced by temperature, so that the detection accuracy of the gas sensor is low. The current gas state parameter value is compensated through the temperature compensation value, and then the target gas state parameter value is obtained, so that the data obtained by the gas sensor is more accurate, and the accuracy of the gas sensor at different temperatures is improved.

Description

technical field [0001] The present application relates to the technical field of gas sensors, in particular to a temperature compensation device and method. Background technique [0002] A gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. With the continuous maturity of gas sensor technology, gas sensors are continuously used in various gas detection scenarios. [0003] During the implementation process, the inventors found at least the following problems in the traditional technology: the current gas sensor has the problem that the data accuracy is easily affected by temperature. Contents of the invention [0004] Based on this, it is necessary to provide a temperature compensation device and method capable of improving the accuracy of gas sensor data in order to address the above technical problems. [0005] In order to achieve the above object, on the one hand, an embodiment of the present invention provides a...
