ESP01S Switch Device

• Housing Installation Structure The entire device features a modular 3D-printed housing, secured with M3 screws. The rear incorporates an integrated mounting clip, enabling tool-free surface mounting on walls or cabinets. The housing includes pre-cut openings for a Type-C port and a buzzer, while internal locating grooves precisely accommodate electronic components, facilitating easy disassembly and maintenance.

  

   

• Core Hardware Configuration The device integrates an ESP01S Wi‑Fi module for wireless signal transmission, paired with an SG90 micro servo as the actuating mechanism to physically toggle a lever. A Type‑C port supplies 5V power, complemented by a buzzer that emits audible signals during operation to indicate system status.

   

• Applicable Use Cases This device can retrofit standard 86-type switches, bedside lamps, and small locks to enable wireless remote mechanical control. Additionally, it serves as an educational tool for makers, providing hands-on demonstrations of IoT communication, servo-driven mechanisms, and enclosure assembly, while supporting custom programming to expand functionality.
