[0018] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.
[0019] Such as figure 1 As shown, the gas alarm uses a high anti-interference methane gas sensing module, including a gas sensor, a control chip, a capacitor, and a module circuit. The gas sensor is used to sense ambient gas and convert the detected gas information into electrical signals and send it to Control chip
[0020] The control chip is equipped with a gas concentration calculation module, a concentration analysis module and a delay linkage module. The gas concentration calculation module is used to calculate the gas concentration according to the signal collected by the gas sensor, and the concentration analysis module is used to calculate the gas concentration obtained by the gas concentration calculation module. The gas concentration is compared...
