Control method of formaldehyde sensor module

Abstract

The invention discloses a control method of a formaldehyde sensor module. The formaldehyde sensor module comprises a shell, a sensor, an electric control switch, a control module and a data interfaceconnector, wherein an assembly cavity and a detection cavity are defined in the shell; the detection cavity is provided with a detection port which is communicated with the assembly cavity; the sensoris arranged in the detection cavity; the electric control switch is arranged in the assembly cavity to open or close the detection port; the control module is arranged on the shell, and is electrically connected with the electric control switch and the sensor respectively; the data interface connector is suitable for performing data exchange between the control module and external equipment. Thecontrol method of the formaldehyde sensor module comprises the following steps: performing power on self-test, and recording a power on self-test result; when the self-test result indicates a success,entering a standby state, scanning a signal of the data interface connector, performing an operation according to a communication instruction transmitted by the external equipment, and restoring to the standby state after the operation is completed. By adopting the control method according to the embodiment of the invention, the reliability of a detection result is facilitated.

Description

Technical field [0001] The invention relates to the technical field of detection equipment, in particular to a control method of a formaldehyde sensor module. Background technique [0002] Devices involving air detection and processing will be equipped with air sensors to detect air. With the operation of the equipment, the air composition, temperature and humidity and other parameters will change, and this change will be caused by the air, objects and personnel caused by the environment. Changes due to exchange, if certain important parameters of the air cannot be detected, it will affect the performance of the equipment, and even threaten the range of activities and health of the personnel in the space monitored and controlled by the equipment. In the space where air conditioning equipment is used, the inability to detect the specific gas content in the air will cause the deterioration of air quality, making it difficult to take effective countermeasures, which will harm the he...

[0002] Devices involving air detection and processing will be equipped with air sensors to detect the air. With the operation of the equipment, parameters such as air composition, temperature and humidity will change, and this change will be caused by the interaction of air, objects and personnel with the environment. Changes due to exchange, if some important parameters of the air cannot be detected, it will affect the performance of the equipment, and even threaten the range of activities and health of the personnel in the space measured and controlled by the equipment

In the space where air-conditioning equipment is used, the failure to detect the specific gas content in the air will lead to the deterioration of air quality, making it difficult to take effective countermeasures, which will cause harm to the health of personnel and even threaten the lives of relevant personnel
