The core function of the controller is to read current values from the sensors, and this is done in the current_values<\/a> module. In order to make the design extensible, the sensor types are handled by sensor helper modules dropped into the sensor_helpers<\/a> directory. The __init.py__<\/a> file just has to be updated to include the reference to the new sensor type.<\/p>\n

The skeleton controller includes one sensor type – evaluate, which enables us to read the virtual sensor described in a previous post<\/a>. To run the controller, without rebooting the pi, use the following command:<\/p>\n

sudo su - -c \/etc\/rc.local<\/pre>\n
and inspect the logfile for any errors:<\/p>\n
cat \/var\/log\/hub\/hub.log<\/pre>\n
and view the statistics on the website:<\/p>\n

You should now see the sensor value changing every minute. It should be tracing out a sine wave, but we will need the graph features in later modules to prove this! \u00a0What we should do now is connect up a real sensor.<\/p>\n","protected":false},"excerpt":{"rendered":"
