| Once connected to Wi-Fi, the program sends the data to the web server though the WebServer.h library, which is responsible for HTTP requests. In order to view the data, I created an HTML page using Aynchronous JavaScript and XML (AJAX). Using this language, it is possible to update values asynchronously, without the need of refreshing the whole page. | Once connected to Wi-Fi, the program sends the data to the web server though the WebServer.h library, which is responsible for HTTP requests.

| + | ====== Problems encountered ====== | ||
| + | |||
| + | Even though this project seems pretty simple in hardware terms, the hardware itself was a nightmare to deal with. I initially ordered a variant of the GY-MAX30100, namely RCWL-0530 MAX30100, but when I tried to route it to the microcontroller, it failed to connect. While reading online, I came across [[https://www.teachmemicro.com/max30100-arduino-heart-rate-sensor/ | this article]], which outlined the problem with the sensor that I had. Because of this, I would be required to remove three resistors from its surface, or buy its variant, which I ultimately had to do. This sensor ultimately had no problems, and I managed to work through the project just fine. | ||

| + | ====== Conclusions ====== | ||
| + | |||
| + | Seeing the sensor do its job and present data as advertised is something of great impact. Not only do you see real life sensors come into play, but you also have the opportunity to interact directly with them. This project was a window of opportunity for me to delve deeper into the IoT world. Already working for clients in the IoT space, it was an opportunity to get more hands-on work with the actual sensors themselves, and this was a satisfying experience. | ||
