waterproof spherical iot device 3d model

A detailed 3D model of a waterproof spherical IoT device designed for monitoring fish temperature inside an ice cooler box. The sphere is split into two halves (top and bottom shell) with a visible rubber O-ring seal in the middle joint. The outer shell is smooth matte white plastic with subtle grip texture. The model includes an internal cutaway view showing components: - A temperature sensor placed near the inner wall of the sphere, slightly protruding toward the outside - A central ESP32 microcontroller mounted securely in the middle - A cylindrical 18650 battery positioned at the bottom for weight balance - Internal mounting brackets holding components in place - A small silica gel compartment for moisture control The design emphasizes waterproof engineering, with clean cable routing and sealed structure. The sphere is slightly weighted at the bottom to maintain stable orientation in water or ice. Highly detailed, realistic product design, clean industrial design, soft lighting, studio render, exploded
