Overview

The flame sensor can detect flame and infrared light sources with wavelengths ranging from 760 nm to 1100 nm. It uses the LM393 comparator chip, which gives a clean, stable digital output signal and driving ability of 15 mA.

This flame detector that can be  used in fire alarms and other fire detecting devices.

Specifications

• LM393 comparator chip
• Detection Range: 760 nm to 1100 nm
• Operating Voltage: 3.3 V to 5 V
• Maximum Output Current: 15 mA
• Digital Outputs: 0 and 1
• Detection Angle: about 60 degrees
• Adjustable sensitivity via potentiometer
• LED lights indicators: power (red) and digital switching output (green)
• Fixed bolt holes for easy installation
• PCB Size: 32 x 14 mm

Note: The sensor should be placed at a reasonable distance from the flame, in order to prevent damage due to high temperature.
