Medical device storage management program development
Medical device storage management program development
I. Overview
Record the storage time of the equipment and the time it leaves. The temperature and humidity can be displayed on the screen, LED lights can be turned on and off, and the size of the fan can be adjusted. It can communicate with the host computer through WIFI and 3G, and manage the use of the device through the host computer.
The product adopts STM32 processor platform, with WIFI and 3G communication, with temperature and humidity check function, etc., with 7-inch LCD screen and capacitive touch screen.
