SPECIFICATIONS

Flame Sensor Module

This sensor detects for flame wavelengths between 760 nm to 1100 nm infrared and is most sensitive. The module has two outputs:

• AO - analog output, real-time output voltage signal on the thermal resistance
• DO, when the temperature reaches a certain threshold, the output high and low signal threshold adjustable via potentiometer; 60 degree detection sensor.
• LM393 comparator chip
• Detection Range: 760 nm to 1100 nm
• Operating Voltage: 3.3 V to 5 V
• Maximum Output Current: 15 mA
• Digital Outputs: 0 and 1
• Detection Angle: about 60 degrees
• Adjustable sensitivity via potentiometer
• LED lights indicators: power (red) and digital switching O/P (green)
• Please keep a distance with flame, high temperature maybe burn out the sensor module.

WORKING

Welcome to the Arduino Based Project which consists of Flame Sensor and Relay Module. The basic functionality of Flame Sensor is being described here.When fire burns it emits a small amount of Infra-red light, this light will be received by the Photodiode (IR receiver) on the sensor module. Then we use an Op-Amp to check for change in voltage across the IR Receiver, so that if a fire is detected the output pin (DO) will give 0V(LOW) and if the is no fire the output pin will be 5V(HIGH). The flame detector has functions of collecting, processing input signals and output control signals.

Also, when Arduino checks the logic level on the output pin of the sensor and performs further tasks such as activating the buzzer and LED, sending an alert by turning on the Water Pump motor. This system acts as firefighting bot which is activated when Fire is being detected by module.
