The KY-026 Flame Sensor Module is designed to detect open flames and other light sources emitting wavelengths between 760 nm and 1100 nm. It features both analog and digital outputs: the analog output provides a voltage proportional to the detected flame intensity, while the digital output activates when the flame intensity exceeds a user-defined threshold, adjustable via an onboard potentiometer. This module is ideal for fire detection systems, flame alarms, and firefighting robots.
