Creating automated alerts based on the measured data
Monitoring several ESP8266 modules at once
Troubleshooting common issues with web services
Introduction
In this chapter, we will be looking at cloud data monitoring using the ESP8266. The ESP8266 is an ideal chip for IoT projects since it offers Wi-Fi connectivity as well as basic GPIO pin functionality. To demonstrate all that, we will use the ESP8266 to read sensor data and log it to and retrieve it from online servers. We will also look at other different features of IoT platforms that we can use to secure and monitor our data.
