Main Description
“The Flame Sensor Module uses a high-speed NPN silicon phototransistor that is particularly sensitive to the infrared radiation emitted by a flame. The module incorporates an LM393 voltage comparator, providing a stable digital output (DO) for quick alerts and an analog output (AO) to measure the flame’s intensity or proximity. This sensor is highly directional and most effective when pointed directly at the potential fire source.
Key Features:
-
Spectral Sensitivity: Optimized for the detection of 760nm to 1100nm wavelengths (standard fire flame spectrum).
-
Dual Output Mode: Digital output for threshold-based alerts and Analog output for flame intensity mapping.
-
Adjustable Sensitivity: Features an on-board potentiometer to fine-tune the detection distance and trigger level.
-
Long Range Detection: Capable of detecting an ordinary lighter flame at a distance of up to 80cm.”
