Flame Sensor

Integrated Flame Detection Module for Real‑Time Fire Safety

The Flame Sensor is a solid‑state optical device designed to detect combustion flames with high reliability and minimal false triggers. It employs a dual‑band photodiode array that captures the characteristic infrared (800 nm) and visible (650 nm) spectra emitted by active flames, enabling quick discrimination against ambient illumination. Commonly integrated into industrial fire suppression systems, furnace monitoring, and automatic shut‑off circuits, it provides a low‑power, plug‑and‑play solution for hazardous environment protection.

• Key Spec 1: Dual‑band (IR & Visible) sensitivity with a detection range up to 50 m for turbulent flames.
• Key Spec 2: Response time < 200 ms, ensuring rapid relay activation in critical scenarios.
• Key Spec 3: Operating temperature –20 °C to +85 °C; IP66 sealed housing for dust and splash protection.
• Common Use Case: Automated suppression in gas furnaces, boiler alarms, and high‑temperature process equipment.
