1-Channel Flame Sensor Module for Arduino – Adjustable & High Sensitivity

1-Channel Flame Sensor Module for Arduino – Adjustable & High Sensitivity

The 1-Channel Flame Sensor Module is a compact and highly sensitive electronic module designed to detect flames by sensing infrared (IR) radiation emitted from fire sources. This sensor is ideal for use with Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontroller platforms, making it a popular choice for safety systems and educational electronics projects.

The module is built on a durable blue PCB and features a precision infrared flame detection diode, a comparator IC, and an onboard adjustable potentiometer that allows users to fine-tune the detection sensitivity based on environmental conditions.

Key Features

• High-sensitivity infrared flame detection

• Detects flame or fire sources quickly and accurately

• Adjustable sensitivity via onboard potentiometer

• Digital output for easy microcontroller interfacing

• Compact, lightweight, and low power consumption

• Power and detection indicator LEDs for visual status

Working Principle

The flame sensor works by detecting infrared light in the wavelength range of approximately 760 nm to 1100 nm, which is typically emitted by flames. When a flame is present, the sensor detects the IR radiation and sends a signal to the onboard comparator.

• When the detected IR level exceeds the preset threshold, the digital output (DO) changes its state.

• The sensitivity can be adjusted using the blue trimmer potentiometer, allowing accurate detection in different lighting environments.
