| ====== Challenges ====== | ====== Challenges ====== | ||
| + | Sensor Accuracy and Timing | ||
| + | |||
| + | * Differentiating between entry and exit requires precise detection and timing. | ||
| + | * Simultaneous movement or people hesitating at the doorway can cause incorrect counts. | ||
| + | * Solution: Implemented a state machine with timeouts to improve reliability. | ||
| + | |||
| + | Resource Limitations on ESP32 | ||
| + | |||
| + | * Hosting a full HTML page, JavaScript logic, and handling concurrent client requests pushed the memory limits. | ||
| + | * Optimized the web page content and avoided large libraries to keep the firmware lean. | ||
| + | |||
| + | Security Considerations | ||
| + | * Password is sent in plain text and checked locally, making it vulnerable in open networks. | ||
| + | * Future improvements could include HTTPS support or token-based authentication. | ||
