    Description

    The Flame Sensor Relay Module is a highly sensitive and practical fire detection solution designed for safety and automation systems. Operating within the 760nm–1100nm infrared wavelength range, it accurately detects flame sources at distances up to 80cm, depending on flame intensity. Because it features an onboard 10A relay, the module can directly control high-current devices such as alarms, exhaust fans, or even disconnect 220V AC loads during fire incidents. Moreover, the adjustable sensitivity potentiometer allows precise tuning based on environmental conditions. Its 60-degree detection angle ensures wider coverage, while the compact 50×26mm board with mounting holes simplifies installation. Featured By RoboticsBD.

    Features:

    1. Wide Infrared Detection Range – Detects flame signals between 760nm and 1100nm for accurate fire sensing.

    2. Long Detection Distance – Identifies flame sources up to 80cm, depending on flame size and intensity.

    3. High-Power Relay Output – Controls loads up to 250V AC / 10A or 30V DC / 10A directly without additional driver circuits.

    4. Adjustable Sensitivity Control – Fine-tune detection threshold using the onboard potentiometer for different environments.

    5. Stable Comparator Circuit – Ensures accurate triggering and minimizes false alarms.

    6. Wide 60° Detection Angle – Provides better coverage compared to narrow-angle sensors.

    7. Compact & Mountable Design – Includes mounting holes for secure installation in panels or enclosures.
