For me, the ease of WiFi, and the Arduino compatibility meant that I was able to get up and running much faster. Not having a background in electrical engineering, the simple things like having a good base with the PCB, a couple sensors built-in and easy expansion makes all the difference.</p> <p>Before the ESP chips, I&rsquo;d tried several other wireless communication chips that were each challenging in their own way. Since my ultimate goal is to report the sensor data to a monitoring service, getting up the stack so that I could use IP communication was a big win, and the ESP chips are perfect for this.</p>
