IR Infrared Flame Sensor Module

IR Infrared Flame Sensor Module Overview

The IR Infrared Flame Sensor Module is a compact, reliable device that detects flame signatures using infrared sensing technology. Designed for easy integration with development boards and microcontrollers, this module is suitable for fire detection, safety automation, robotics, and educational projects.

Key Features

• Sensitive infrared detection for quick and reliable flame identification
• Wide operating voltage: 5V to 12V for compatibility with many systems
• Dual outputs: analog output (AO) for measurement and digital output (DO) for threshold-triggered alerts
• Adjustable sensitivity via onboard potentiometer to tune detection range and false-alarm resistance
• Compact and lightweight form factor ideal for tight spaces and embedded systems

Technical Details and Typical Connections

• Operating voltage: 5V to 12V DC
• Outputs: Analog output (AO) and Digital output (DO)
• Typical module pins: VCC, GND, AO, DO (pin names may vary by manufacturer)
• Sensitivity: Adjustable with potentiometer (onboard)

Integration and Wiring Tips

• Power: Connect VCC to a stable 5V to 12V supply and GND to ground.
• Analog integration: Connect AO to an analog input (ADC) on Arduino, Raspberry Pi via an ADC, or other microcontrollers to measure intensity.
• Digital integration: Connect DO to a digital input to receive a HIGH/LOW alert when the module detects a flame above the set threshold.
• Adjust sensitivity: Use the potentiometer to reduce false positives from ambient IR sources or increase sensitivity for long-range detection.
• Signal conditioning: Add simple filtering or debounce logic in software when using DO to avoid rapid toggling from flickering sources.

Common Applications

• Fire alarm and early-warning systems
• Safety automation in workshops and factories
• Robotics and autonomous systems with hazard detection
• Smart home fire monitoring and integration into home automation
• Educational demonstrations and electronics projects

Mounting and Placement Advice

• Mount the sensor where it has a clear line of sight to the monitored area.
• Avoid placing the sensor directly facing heat sources that are not flames to minimize false triggers.
• For indoor use, keep the sensor away from bright IR sources (e.g., sunlight through windows) or use shielding.

Compatibility

• Works well with Arduino, Raspberry Pi (with ADC), ESP8266/ESP32, and most microcontroller platforms.
• Software: Read AO via ADC or read DO as a digital interrupt/polling input.
