Flame/Fire Sensor Module

Description:

• A flame sensor module is an electronic device designed to detect the presence of a flame or fire. It typically operates by detecting the infrared (IR) radiation emitted by flames.
• These modules are widely used in applications where fire detection is essential, providing a rapid response to potential fire hazards.

Key Features:

• Infrared Detection: Primarily detects flames by sensing IR radiation.
• Adjustable Sensitivity: Many modules feature a potentiometer to adjust the sensitivity of flame detection.
• Digital and Analog Outputs: Often provides both digital (on/off) and analog (variable voltage) output signals.
• Fast Response Time: Designed for quick detection and response to flames.
• Wide Detection Angle: Typically offers a wide detection angle, allowing for broad coverage.
• LM393 Comparator: Many modules utilize an LM393 comparator chip for stable readings.
• Wide Voltage Operation: Usually operates within a voltage range of 3.3V to 5V.

Applications:

• Fire Alarm Systems: Used in residential and industrial fire alarm systems.
• Fire Fighting Robots: Integrated into robots designed for firefighting operations.
• Industrial Furnace Monitoring: Used to monitor flames in industrial furnaces and boilers.
• Gas Leak Detection Systems: Can be used in conjunction with gas sensors to detect and respond to gas leaks and fires.
• Home Automation: Can be incorporated into smart home systems for fire safety.
• Safety Systems: Used in various safety systems to detect and respond to potential fire hazards.

Specifications:

• Operating Voltage: 3.3V - 5V
• Detection Range: Varies depending on the module and flame intensity, often up to 1 meter.
• Detection Angle: Typically around 60 degrees.
• Wavelength Range: Sensitive to light in the 760nm to 1100nm wavelength range.
• Output: Digital (DO) and Analog (AO)
• Comparator: LM393
