Outcome

The final outcome is a device which has all the functionalities mentioned above i.e. sensing the stove indicator from the stove panel, lighting up an LED from green to red if the threshold is crossed, giving an audio signal to alert people in the house and also send an email to the housemates just in case nobody is at home. The prototype is fully functional and all it needs is a casing/fabrication and fitting on the stove panel. It also could be integrated with a thermal sensor for improved results.
