1. Sensor Element:

• The module typically includes a flame sensor element, which can be based on various technologies such as infrared (IR) sensors or ultraviolet (UV) sensors. These sensors are sensitive to the characteristic wavelengths emitted by a flame.

2. Sensing Range:

• Flame sensor modules have a specified sensing range within which they can effectively detect the presence of a flame. This range is influenced by the type of sensor technology used.

3. Signal Output:

• When a flame is detected, the module generates an electrical signal, often in the form of a voltage or current, which can be used as an input to a microcontroller or a control system.

4. Sensitivity Adjustment:

• Many flame sensor modules come with sensitivity adjustment features, allowing users to fine-tune the sensor’s response to different flame intensities or environmental conditions.

5. Output Indicator:

• Some modules have built-in LED indicators or other output mechanisms to visually indicate when a flame is detected. This feature can be useful for testing and troubleshooting.

6. Compatibility:

• Flame sensor modules are designed to be compatible with various microcontrollers and control systems. They often have standard interfaces, making them easy to integrate into different electronic circuits.

7. Operating Voltage:

• The module operates within a specific voltage range, and users need to ensure that the voltage requirements match the power supply in their application.

8. Environmental Considerations:

• Flame sensor modules are designed to operate in specific environmental conditions. Users should be aware of temperature, humidity, and other factors that might affect the sensor’s performance.

9. Applications:

• Flame sensor modules find applications in gas stoves, water heaters, industrial furnaces, and fire detection and suppression systems.
