| + | Working on this project was both challenging and fun. At first, I wasn’t sure if everything would work together, especially the SIM800L module, which needed a lot of trial and error to set up properly. I also had to be careful with wiring and power, since I didn’t want to damage any components. | ||
| + | |||
| + | I learned a lot about how to use interrupts, how UART communication works, and how to read data from the DHT11 sensor. I also got some practice debugging both hardware and software issues, which sometimes took a while but felt great once they were solved. | ||
| + | |||
| + | In the end, I managed to build a system that detects high temperatures, triggers an alarm, and sends an SMS alert. It even has a button to silence the alarm, which works using interrupts. | ||
| + | |||
| + | Even though it’s a simple version, I think it’s a good starting point, and I’m happy with how it turned out. With more time, I’d like to improve the design and maybe add more features. Overall, it was a great learning experience. | ||
