Title:
GAS CONCENTRATION MEASUREMENT METHOD AND GAS MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/179558
Kind Code:
A1
Abstract:
Embodiments of the present application provide a gas concentration measurement method and a gas measurement device. The method comprises: after a zero reference value calibration time is reached, measuring a gas concentration in the environment to obtain a first value; if the first value satisfies a preset condition; updating the current zero reference value according to a preset rule to obtain a new zero reference value; and correcting, by using the new zero reference value, a gas concentration measurement value subjected to the update of the zero reference value. The method can improve the accuracy of gas concentration measurement.
