Flame Sensor Module with infrared detection for Arduino and DIY projects. Supports 3-pin and 4-pin versions with adjustable sensitivity, digital and analog outputs for fire detection applications.
Flame Sensor Relay Module with infrared detection and 5V relay output. Designed for Arduino, DIY fire alarm systems, and automatic control projects with adjustable sensitivity.
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.
