Atmel board is integrated with temperature and humidity sensor, VOC sensor and dust sensor, provided by Michael Wang. To read data from sensors, we need to run our C code in Atmel Studio 7.0.
After starting the C code, we need to connect the corresponding port for data visualization in Atmel Studio Terminal, which is convenient to see if the board is working and what data is being posted.
The Atmel board hasn't been connected to Wi-Fi yet. The next step is Wi-Fi provisioning. Connect local machine to a Wi-Fi named FutureAir_xxxx (xxxx is a four-digit combination of letters and numbers corresponding to the board's Wi-Fi chip). Open any browser, preferably Chrome or Safari, and the provisioning web page will open automatically.
After Wi-Fi provisioning, Atmel board can finally post data to our AWS OpsWorks Node.js server. The terminal output should be something like this if provisioning is successful.
Now, real-time data is being posted on our server. The data will then be stored in AWS RDS database and visualized in our ThingSpeak channel.
