Model Railroad Internet of Things Projects - Using ESP32 and Raspberry Pi

This book is a great resource in the use of Wi-Fi enabled microcontrollers, demonstrated by several Internet-Of-Things applications of the ESP32 devices on small model railroads.

The ESP32 is a powerful WiFi/Blutooth-enabled System on Chip device that lets the programmer do a variety of functions.  The authors show ways to connect them to sensors, turnouts, and transfer information to computers by using Wi-Fi technology. 

The first sections in the book provide guidance and demonstrate various capabilities to utilize the ESP32 along with the Mosquitto MQTT Broker.  The final section of the book uses techniques from the earlier chapters to complete several applications on model railroad layouts including: capturing data using infrared sensors to determine if sidings are occupied, determine the speed of trains on a layout, and a Wi-Fi DC throttle. 

This book is intermediate level based on the complexity of IOT systems but it is constructed in a way to aid a novice in gaining experience to complete the advanced applications and expand the reader's own model railroad projects.
