Flame Sensor Module IR Infrared Fire Detection for Arduino
Add a critical layer of safety to your projects with this Flame Sensor Module. This sensor is specifically designed to detect the infrared (IR) radiation emitted by a flame or other high-temperature light sources, making it an essential component for creating fire alarms, robotic firefighters, or automatic safety shut-off systems.
The core of this module is a highly sensitive infrared photodiode that responds to IR wavelengths in the 760nm to 1100nm range, which is characteristic of a fire. The sensor can detect a flame from a distance and has a detection angle of about 60 degrees. The onboard LM393 comparator processes the signal from the photodiode. When the detected IR intensity exceeds a set threshold, the digital output (DO) pin changes state, providing a clear signal to your microcontroller.
You can easily adjust the sensitivity and detection distance using the blue potentiometer on the board. This allows you to fine-tune the sensor to avoid false positives from other light sources. Note: While designed for flames, the sensor can also be triggered by other strong IR sources like direct sunlight or IR remote controls, so placement is key for reliable operation.
Key Features:
- Sensing Spectrum: Detects infrared radiation in the 760nm – 1100nm range, specific to flames.
- Adjustable Sensitivity: Onboard potentiometer to set the detection threshold.
- Output Type: Digital logic output (HIGH/LOW) for easy integration.
- Wide Detection Angle: Approximately 60 degrees for broad coverage.
- Operating Voltage: 3.3V to 5V, compatible with Arduino, ESP32, and other microcontrollers.
Applications:
This module is ideal for building fire detection and alarm systems, safety devices for kitchens or workshops, firefighter robots, and any project that needs to react to the presence of a flame.
