7.7 The Flame Sensor

A flame sensor (IR receiving diode) is specifically used on robots to find the fire source. This sensor is highly

sensitive to flames.

A flame sensor has a specifically designed IR tube to detect fire. The brightness of the flames will then be

converted to a fluctuating level signal. The signals are the input into the central processor.

Required Hardware

 1 x flame sensor

 1 x buzzer

 1 x 10KΩ resistor

 1 x breadboard

 jumper wires as needed
