When an ESP8266 encounter MQTT and an accelerometer

This is a project I built for a presentation at on November 21st.

  • some experience with MQTT and I2C
  • see how much I can push the Esp8266
It was an interesting challenge!
Check the slides on my previous post to learn more about the project.
In my final demo I had:
Feel free to write me if you want to repeat the project and need helps.

ESP8266 and IOT talk at Codemotion Milan 2015

I was a bit far from the blog.. but it was because I was preparing a talk for

I built a demo using nodemcu, esp8266, mqtt, mosquitto, nodejs and adxl345.
Shortly: reading raw data from accelerometer (x,y,z) and send that data with MQTT through wifi.

More info coming veeeery soon..with sourcecode!
