Subject to errors and changes
The following reading function is used for this:
function sensorChanged( iDevice, iSensor, iVal )
{ Program code run when there is a change on the inputs
The above function is invoked by the applet when a temperature
change on the sensors is detected. iDevice specifies for which
Web-Thermograph a value changed. iSensor is used to indicate
which sensor changed. The variable iVal transmits the current
temperature value.
!
Please note that the names of the functions are
case-sensitive
