The data displayed below is an image of what is retrieved from this TINI HTTP Server. Values from 5 different sensors can be read through the Analogue to Digital Converter (ADC) on the Tutor board. A Multiplexer is used to select the channel to be displayed.
The graph below shows the temperature over a 24 hour period. A program simply records a temperature value to file every hour. At the end of the 24 hour period the program reads all the values from the file and creates a graph in HTML code. Therefore the graph below could be updated at the end of each day and the values displayed are from the previous day.
