Flame Sensor Module

Introduction This module is sensitive to the flame and radiation. It also can detect ordinary light source in the range of of a wavelength 760nm-1100 nm. It can be used as a flame alarm or in fire fighting robots. Features • Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm. • Detection range: up to 50 cm. • Adjustable detection range. • Detection angle about 60 degrees, it is sensitive to the flame spectrum. • Comparator chip LM393 makes module readings stable. • Operating voltage 3.3V-5V. • Digital and Analog Output. • Power indicator and digital switch output indicator.
