Flame Sensor Module

From the shop's description

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.
