5-Channel Flame Detection Sensor Module – 120° Wide-Angle Analog & Digital Output

The 5-Channel Flame Detection Sensor Module is designed to provide wider and more directional flame detection than a conventional single-sensor flame detector.

Using five flame-sensitive infrared sensors positioned across the board, the module provides a combined detection angle of more than 120° as specified, making it particularly useful for fire-fighting robots, flame-tracking robots, alarm systems, Arduino projects, and robotics experiments.

Both digital and analog outputs are available, allowing the module to be used for simple flame detection as well as applications that require more detailed sensor readings.

Wide-Angle Flame Detection

A conventional single flame sensor typically covers a relatively narrow detection area. This module uses five sensors arranged across different directions to increase the overall field of detection.

The combined arrangement provides a detection coverage of more than 120° as specified, allowing a robot or monitoring system to detect flames across a wider area.

The effective detection distance and angle will vary depending on flame size, distance, sensor orientation, ambient infrared light, sensitivity adjustment, and environmental conditions.

Analog & Digital Outputs

The module provides both digital and analog signal outputs.

The digital outputs can be used for straightforward flame/no-flame detection, making them easy to interface with microcontroller GPIO pins.

The analog output provides a variable voltage signal related to the detected infrared intensity, allowing a microcontroller to compare readings and obtain more detailed information about the flame signal.

Adjustable Sensitivity

The module allows adjustment of the digital detection threshold and analog sensitivity as specified, providing additional flexibility when configuring the sensor for different operating environments.

Five onboard status indicators provide visual feedback from the sensing channels, which is particularly useful during setup, calibration, and troubleshooting.

Flame-Tracking Robot Applications

The five-channel configuration is particularly useful for fire-fighting and flame-tracking robots.

By comparing the signals detected by sensors facing different directions, a microcontroller can determine the approximate direction of a flame and command the robot's motors to move or turn toward the detected source.

Applications

Ideal for Arduino projects, fire-fighting robots, flame-tracking robots, robotics competitions, fire detection experiments, alarm systems, STEM education, autonomous robots, embedded-system projects, and infrared sensing experiments.

Important Note

This module detects infrared radiation associated with a flame and should not be treated as a certified fire or life-safety detector.

Sunlight, incandescent lamps, and other infrared sources may affect detection performance. Sensitivity and threshold settings should be calibrated for the actual installation environment.

When connecting the module to a 3.3V microcontroller, verify the output voltage levels before connecting signals directly to the controller's GPIO or ADC pins.
