Description
The KY-026 Flame Sensor Module is an infrared light sensor designed to detect fire or flames within the 760nm–1100nm wavelength range. Ideal for Arduino, Raspberry Pi, and microcontroller projects requiring flame or light-based detection.
This module outputs both analogue and digital signals. The analogue output reflects the intensity of the detected flame, while the digital output activates when the signal passes a user-defined threshold (adjustable via an onboard potentiometer). The sensor is particularly useful in fire alarm systems, safety monitoring, and robotic fire detection.
