5-Channel Flame Detector for Arduino or Raspberry Pi

5 Independent Flame Sensors

Use this module to detect flame over broad range ( >120 degree). It recognizes the fire using five independent sensors arranged with 30 degrees of separation. The module outputs both an analog signal (value varies with the intensity of sensed flame) and also a digital signal well suited to microcomputer applications. The onboard potentiometer can adjust the digital output sensitivity level. The 5 built-in LED indicators will assist in debugging and testing of the system.

Mounting for the sensor board is by three M3 mounting holes for easy installation.

Working Principle

Detects flame band in the range of 700-1100 nm, short-wave near-infrared (SW-NIR) and triggers an output via an electric signal when sensed.
