This project is to put The Shed's lighting controls on the internet, and to monitor the air quality in The Shed throughout the day.

You will want to make this point to your server. To do this, change MQTT_HOST and MQTT_PORT as defined in mqtt_client.h.

• MQTT support
• Sensor data reported once per 5s over MQTT_PORT
• Light state may be changed by publishing mesasges to the sjc80/set_lights topic
• Sensors available:
• DHT22 Humidity and Temperature sensor
• GP2Y10 Particle Counter (experimental)

There is no security built in. You can run this on a LAN only, which is preferential to exposing the light switch over the internet; however to keep the client simple (all js speaking to MQTT) adding authentication was not a sensible design option.

With the gcc arm tools available on your path, you should be able to do:

make -j4

# modify for wherever you mount your mbed
cp ./frdm_shed_lights.bin /media/mbed

to build and deploy to an FRDM K64F development board.

On Windows, I suggest installing Cygwin with GNU Make to execute the Makefile.
