5-Channel Flame Sensor Module is a 5 channel flame detector module used to detect flame in larger area( >120 degree). If you need a robot which should detect any fire around, then this module will be very useful for you. It detects the fire with 5 flame sensors which are arranged with 30 degrees. This module outputs analog signal, which would be more precisely, and also digital signal which would be more easy to use, you can adjust the digital output sensitivity by the on-board potentiometer. The 5 LED indicators are helpful in your debugging, the high-precision resistors also makes this sensor more precise than other flame sensors.
