Description

1. Working Principle: Flame sensors typically work based on the principle of detecting the infrared (IR) or ultraviolet (UV) radiation emitted by a flame.
2. Types:
   • IR Flame Sensor: This type of sensor detects the IR radiation emitted by a flame. It is sensitive to the wavelengths of light produced by flames.
   • UV Flame Sensor: UV flame sensors are designed to detect the UV radiation generated by a flame.
3. Detection Range: The detection range of a flame sensor can vary depending on the specific model, but it’s generally within a few meters.
4. Sensitivity Control: Many flame sensor modules include a sensitivity adjustment potentiometer, allowing you to fine-tune the sensor’s sensitivity to different flame intensities.
5. Analog or Digital Output: Flame sensors can provide analog or digital output signals based on the detected flame’s intensity. Some models provide a simple digital HIGH/LOW output, while others provide an analog voltage that corresponds to the flame intensity.
6. Response Time: Flame sensors typically have a fast response time, enabling them to quickly detect the presence of a flame.
7. Indicator LEDs: Some modules include indicator LEDs that light up when a flame is detected, providing a visual indication.
8. Operating Voltage: Flame sensors usually operate at a low voltage, often around 5V DC.
