A small Wi-Fi-intelligent microscope system is proposed to get rid of the problems of the traditional microscope's complicated operation, large volume, and limited light source. The common network camera CMOS circuit is used as the microscope's imaging circuit, and the network camera's advantage is reasonably utilized. The communication module adopts network communication between the computer and the microscope, utilizing the AP function of the ESP8266 module. The image can be transmitted to the upper computer software to set the camera parameters and save the image. The cost is low because the mechanical structure of the microscope is designed using NX12.0 software and three-dimensional printing technology. Consequently, the whole system works in conjunction, and the cell image is collected through the microscope.
