The "IoT Deployment Board" is a very simple board that practically works a as extension of the ESP8266-01 module, but, with some values adds like; pre-programmed with a fresh MicroPyhton version adapted for this microcontroller, amplified outputs to drive more current, convenient output connector, output protection, led indicators, internal 3.3V regulator, wide range of power supply, battery operation, I2C, 1-W protocols supported for different type of sensors, amount others features included. With this board user can make all projects come true using almost any kind of sensor including: temperature, humidity, PIR, ultrasonic, OLED display, RGB LEDS, NeoPixel, amount any other project like: web server station, Wi-Fi connections, personal web page, dashboard instrumentation, MQTT server, etc. Since Python is a programming language that is widely supported for Python community, with very high probability user will find sure a support for all projects.In this book It has been prepared a very comprehensive introduction about the board itself and the MicroPyhton, for a more complete material for all users and levels, including students, amateurs, and engineers, and of course, a very extensive part is developed about connecting, using and programming a variety type of sensors, describing the whole thing, including wiring, specifications, experiment and code examples with some application. A practical point of view, that helps in doing this type of projects much more easily.All the code examples that are described here have being already tested and proved to work in the IoT Deployment Board, with all sensors and devices as described in their respective sections.Additionally, all codes are free to copy, modify or try as it is. All examples can also be downloaded (from site).Finally, the author hopes this book can be used as a practical guide to deploy in a much easier way all projects concerning different fields, Wi-Fi, automation, instrumentation, sensing, wireless control, and IoT projects.
