Arduino Flame Detection Sensor Module

This module, designed for Arduino, is capable of detecting flames or light sources by utilizing infrared technology.

Key Features of the Module:

1. Capable of detecting flames or light sources with wavelengths ranging from 760 to 1100 nanometers. It can detect a lighter flame from a distance of 80cm. The detection distance increases with the size of the flame.
2. The module has a detection angle of approximately 60 degrees and is especially sensitive to the flame spectrum.
3. The sensitivity of the module can be adjusted using the blue digital potentiometer shown in the image.
4. The module provides a comparator output, offering a clean signal, good waveform, and strong driving ability of more than 15mA.
5. The module comes with an adjustable precision potentiometer for sensitivity tuning.
6. The working voltage of the module ranges from 3.3V to 5V.
7. The output form of the module includes DO digital switch output (0 and 1) and AO analog voltage output.
8. The module has fixed bolt holes for easy installation.
9. The size of the small board PCB is 3.2cm x 1.4cm.
10. The module utilizes a wide voltage LM393 comparator.

Instructions for Use:

1. The flame sensor is highly sensitive to flames but also reacts to ordinary light. It is typically used for flame alarms and similar applications.
2. The output interface of the small board can be directly connected to the IO port of a single-chip microcomputer.
3. Ensure a safe distance between the sensor and the flame to prevent damage due to high temperatures. The flame distance for a lighter is 80cm, and this distance increases with the size of the flame.
4. The small board provides an analog output mode and AD conversion processing for higher accuracy.
