[0002] In cold chain monitoring, medicine display cabinets, medicine refrigerators, and medicine insulation boxes are equipped with temperature and humidity monitoring systems. This system collects, records, and uploads temperature and humidity data in the target enclosed space. The system is divided into two parts: monitoring instruments and remote management software. Corresponding monitoring instruments are placed in each space to be monitored to collect and record data in real time, stably, and reliably. The monitoring instruments upload data to the cloud platform wirelessly. The remote monitoring software obtains data from the cloud platform and displays the temperature, humidity, and other parameter information in the current space in real time.

[0003] Currently, most cold chain monitoring instrument sensors on the market are single-channel. When the temperature and humidity data of multiple locations need to be obtained simultaneously in the same space, multiple monitoring instruments need to be placed, which increases the monitoring cost and the difficulty of system construction and takes up more space. When it is necessary to temporarily increase the monitoring location, the only way is to replace the monitoring instrument, which is time-consuming and labor-intensive, and the monitoring data cannot maintain integrity, which is not conducive to continuous and stable monitoring of the environment.

The sensor is connected to the main body by a flexible joint, and a multi-channel temperature and humidity sensor is connected to the flexible joint by a cable;

[0008] A monitoring circuit board is installed in the main body.

[0009] The universal side plate is provided with an omnidirectional card slot inside and can be detachably mounted on the main body.

[0010] The main body includes a front shell and a rear shell, an operation panel is installed on the front shell, a universal multifunctional base is connected to the bottom of the front shell and the rear shell, a universal side panel is installed on the side where the front shell and the rear shell are connected, and three guide grooves are arranged on the universal hanging plate, which respectively cooperate with the horizontal, longitudinal and front snap-fits on the rear shell.
