SCHEMATIC

The hardware implementation is executed by using the Arduino MEGA 2560 card: just connect the active sensor as shown in the figure. Pin A0 is set as an analog input for converting the output voltage of the sensor to the AD.

It is difficult to add the function which allow to measure changes of temperature - D - delta temp. Let say current temperature is 30 deg, by pressing the button display will show D = 0, when tempature will change to 32 deg D=2 ?
