Hardware developments for the Internet of Things (IoT) research projects. These technologies are concurrently used in my practice and teaching, helping students to realize their projects. They also inform the conceptual thinking behind much of my work.
Conceptual framework for embedded systems representative of projects in this section
A number of projects utilize microcontrollers (Arduino, ESP 8266), sensors and actuators.
Custom designed sensor shields for WeMos implementation of ESP8266 chipset. From the left: (A) combination of sensor and actuator shield allowing for servo motor attachments, (B) expanded analog shield with 8 12-bit input pins; (no designation/blue PCB) ESP8266 WiMos microcontroller; (C) PIR-motion, temperature/humidity DHT 11/22, and digital luminosity/lux/light (tsl2561) sensor shield
