Version 2 - Optimized Model

This version is an action-sensing device that can send early warning messages via Telegram. Compared with the first prototype, I have optimized and upgraded it in several aspects:

• 🧩A better designI reserved more space for the power supply compartment to ensure that it can be securely stored inside the case.
• 📐Sensor layoutNowadays, sensors can be more easily installed on the top of devices, making subsequent use and debugging more user-friendly and intuitive for users.
• 💧Waterproof performanceI used strong adhesive and a hot melt glue gun to tightly seal all the compartments, further enhancing the waterproof protection capability of the entire machine.

Overall, this version is not only more practical and easier to assemble, but also more suitable for stable use in everyday scenarios.
