Gas detection sensor device

The invention discloses a gas detection sensor device, which comprises at least one gas sensor of which the internal resistance changes according to gas concentration, a measurement part, a calculation part and an input/ output part, wherein the measurement part measures the output of the gas sensor, the calculation part calculates a detection result according to the gas concentration on the basisof the measurement value of the measurement part, and the input/ output part displays and/ or outputs the detection result to an external terminal. By use of the device, gas concentration change canbe quickly detected. 一种气体检测传感器装置，包括：内阻根据气体浓度变化的至少一个气体传感器、测定部分、计算部分和输入输出部分，其中：测定部分测定气体传感器的输出，计算部分基于测定部分的测定值，根据气体浓度算出检测结果，输入输出部分将检测结果显示和/或输出到外部终端。本发明能够快速检测气体浓度变化。
