Hi,
I am planning to do an automated fire-fighting robot for my HND project, however i cannot find a suitable sensor to detect the candles. Basically i want the robot to work as follows; the sensor senses the candle and the robot (running on tracks like a tank) turns towards the candle and moves towards it. As soon as the LM35s detect the set temperature, a solenoid valve is triggered and the candle is lit off. The process is repeated for neighboring candles. I am using 89C51AC2 micro-controller.
Any recommendations please for a fairly accurate and easy to interface sensor?
Thanks in advance
