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

1-Channel Flame Sensor Module – High Sensitivity Fire Detection for Arduino and IoT Projects

The 1-Channel Flame Sensor Module is designed to detect flame or fire within the infrared wavelength range of 760nm to 1100nm. It features a photodiode sensor with a built-in comparator and adjustable sensitivity using a potentiometer. The module provides both digital (DO) and analog (AO) outputs for flexible use in different projects.

This flame sensor is ideal for building fire detection systems, safety alarms, and IoT-based hazard monitoring with Arduino, ESP8266, ESP32, and other development boards. It is commonly used in home safety, industrial equipment, and student projects across Bangladesh.

Key Features:

• Detection Range: 760nm–1100nm IR (flame spectrum)

• Outputs: Analog (AO) and Digital (DO)

• Adjustable sensitivity via potentiometer

• Operating Voltage: 3.3V to 5V

• Onboard comparator chip (LM393)

• Indicator LEDs for power and flame detection

• Compact size and easy Arduino interface

Applications:

• Flame and fire detection systems

• IoT-based fire safety and monitoring

• Smart home safety automation

• Industrial hazard detection

• School/University electronics projects in Bangladesh

The 1-Channel Flame Sensor Module offers a low-cost, reliable solution for early fire detection and safety in embedded systems and smart environments.
