AI Technical Summary

Technical Problem

Existing gas sensors are prone to errors when detecting preset gas concentrations, resulting in the inability to accurately detect gas concentrations.

Method used

A gas sensor is designed, including a base, a temperature measuring element and a gas sensitive element. The ambient temperature is measured through the temperature measuring element, and the gas concentration is detected in combination with the gas sensitive element. The ambient temperature is adjusted by a temperature control element to reduce errors.

Benefits of technology

It improves the accuracy of the gas sensor under different temperature environments, reduces measurement errors caused by temperature changes, and ensures accurate detection of preset gas concentrations.

Abstract

A gas sensor (2), a battery (100a), an electric device (1000a), and a gas concentration measurement method. The gas sensor (2) comprises a base (20), a temperature measurement element (21), and a gas-sensitive element (22); the temperature measurement element (21) is arranged on the base (20), and is used for measuring the temperature of an environment; and the gas-sensitive element (22) is arranged on the base (20), is spaced apart from the temperature measurement element (21), and is used for measuring the gas concentration of a preset gas in the environment at the temperature. In this way, the concentration of the preset gas can be measured more accurately.
