Introduction: ESP8266 IOTMote
We used an ESP8266 with a Arduino nano, and a DHT11 Temperature Sensor to log changes in Temperature and Humidity at the CuriosityGym Office.
We used the basic code from the following github repo
https://github.com/tuanpmt/espduino
The ESP8266 is flashed with the MQTT/GetPut Binary and the Arduino communicates to the ESP8266 over a serial connection. The above github repo does contain instructions on how to get started with the flashing of the ESP8266 and the connection diagrams.
Step 1: Enclosure
We purchased an empty Camera dome and fitted everything inside it.
A hole was made using a dremel to expose the DHT11 sensor to the external environment.
The connections were made using a general purpose PCB with holes, and we spent a lot of time figuring out how to fit everything inside the dome.
Another hole was made in the bottom of the case to accomodate a 9v DC barrel jack. This was then glued in place.
