MQ Telemetry Transport (MQTT)

18 January 2012 by martin

The whole Internet-of-things idea has really captured my imagination. DIY Sensors and Machine-2-machine computing are becoming a reality thanks to open source projects like Arduino.

Today I stumbled upon a podcast interview on MQ Telemetry Transport, or MQTT, with Andy Piper from IBM. MQTT is an M2M/Internet of things connectivity protocol developed at IBM. Much of the podcast talks about how this technology is being used in home DIY sensor projects. MQTT is based on a "Publish and Subscribe" architecture and requires a Broker to handle the messaging. Although IBM have a few different MQTT Broker implementations, there is an open source implementation of the broker server called Mosquitto  that looks worth experimenting with.

If that wasn't enough to wet your appetite, Andy Stanford-Clark (also from IBM) gave a presentation called "The house that Twitters" which explains how he has used MQTT to create a number of interesting home sensor projects.

Glad the interview caught your interest :-) there are plenty of different implementations around now - and lots of folks using MQTT in their home projects with e.g. Arduino, mbed, Nanode and Netduino! Do join the mailing list and check out mqtt.org/get-involved :-)

Thanks for the pointers to get involved. I have requested membership to the Google group.
