[0054] In summary, the handheld operator integrates multiple sensors such as PM2.5, TVOC, carbon dioxide and temperature and humidity sensors. Among them, PM2.5 is in the upper structure. The handheld operator uses the small fan inside the PM2.5 sensor to drive the airflow. Under the influence of PM2.5 airflow, the detection gas passes through the TVOC sensor, carbon dioxide sensor, and temperature and humidity sensor respectively. Through the characteristics of the sensor itself, the whole detection process can be completed without configuring external airflow drive. For the inlet selection, the air inlet selection of the handheld operator can be selected from the left, right, top and bottom. The pros and cons are analyzed: a. If the left side is selected, there is a situation where the handheld operator is installed against the wall, which will block the air inlet and outlet, affecting the detection; b. If the right side is selected, the same disadvantages as the left side; c. If the upper side is selected, considering the natural sedimentation of dust, it is not ruled out that after a long time, too much dust will affect the detection port of the sensor and affect the accuracy of the detection; d. Selecting the lower side can avoid the impact on the installation position (close to the wall is not affected) and avoid sediment falling into the shell to affect the function. This is the optimal solution.

[0055] In addition, the handheld operator can communicate via a 485 connection line or via a wireless module such as a WIFI module.

[0056] As for the size, the back of the hand operator is sized to be placed inside an 86 box. The overall size is approximately 68*68*31.2mm, which can be placed in any common 86 box on the market (the inner diameter of the 86 box is basically 75*75mm, and the depth varies from 40mm to 60mm), making it easy to promote and apply.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
