3PIN Flame Sensor Infrared Receiver Ignition Source Detection Module

Product Description The 3-Pin Flame Sensor Module is a high-sensitivity infrared receiver specifically designed to detect fire sources or light wavelengths within the range of 760nm to 1100nm. This module utilizes the YG1006 NPN silicon phototransistor, which is highly sensitive to the infrared radiation emitted by a flame. Featuring an onboard LM393 voltage comparator, the module provides a clean digital output (High/Low) that can be adjusted using a multi-turn potentiometer. It is an essential safety component for firefighting robots, fire alarm systems, and industrial ignition monitoring, offering rapid response times and easy integration with microcontrollers like Arduino, ESP32, and Raspberry Pi.

Key Features

• Optimized Flame Detection: Specifically tuned to the infrared spectrum of a flame, minimizing false triggers from standard visible light.

• Adjustable Sensitivity: Features an on-board potentiometer to calibrate the detection distance based on the size and intensity of the flame.

• Dual LED Indicators: Includes a power LED and a status LED that lights up when a flame is detected for instant visual feedback.

• Rapid Response Time: The high-speed phototransistor ensures detection within microseconds, critical for emergency shutdown systems.

• Compact 3-Pin Design: Simplified wiring (VCC, GND, DO) allows for quick deployment in DIY robotics and security prototypes.

Technical Details

• Sensing Element: YG1006 phototransistor encased in black epoxy to filter out ambient visible light.

• Comparator Circuitry: Uses the LM393 stable comparator IC to provide a digital output with high drive capability (>15mA).

• Detection Distance: Capable of detecting a standard lighter flame at roughly 80cm; distance increases with larger flame sizes.

• Spectrum Sensitivity: Peak sensitivity occurs at 940nm, matching the peak emission of most hydrocarbon flames.

• Signal Logic: The Digital Output (DO) is "LOW" when a flame is detected and "HIGH" when no flame is present.

• Operating Temperature: Stable performance from -25°C to +85°C.

• Angle of Detection: Approximately 60 degrees, allowing for directional fire sourcing.

• Voltage Compatibility: Works seamlessly with 3.3V logic (ESP32/Raspberry Pi) and 5V logic (Arduino/8051).

• Power Protection: Low power consumption makes it ideal for battery-operated environmental monitoring.

• Hardware Debouncing: The comparator circuit provides a sharp logic transition, eliminating signal jitter.

• Solder-Friendly Pads: High-quality PCB pads ensure reliable connections for header pins or direct wire soldering.

• Logic Level Consistency: Output voltage scales with the input VCC for easy ADC-free integration.

• Small Form Factor: Slim PCB profile allows for mounting in tight spaces, such as inside robotic chassis.

• ESD Robustness: Designed to withstand minor static discharge during handling and installation.

• Versatile Mounting: Features a pre-drilled M3 mounting hole for secure physical attachment.
