4 Pin/3Pin Flame Sensor Module for Arduino Fire Detector Infrared Receiver Module

Description of Flame and Fire Source Detection Module

1. Functions and Features

It can detect flames or light sources with wavelengths in the range of 760nm - 1100nm (the test distance for a lighter flame can reach 80cm, and the larger the flame, the longer the detection distance).

- Core Advantages:

Detection angle of about 60 degrees, highly sensitive to flame spectrum

Adjustable sensitivity (adjusted via the blue digital potentiometer)

Comparator output, clean signal, good waveform, strong driving capability (>15mA)

Equipped with an adjustable precision potentiometer for flexible sensitivity adjustment

- Operating voltage: 3.3V - 5V

- Output forms: D0 digital switch quantity (0 and 1), AO analog voltage output

- Equipped with fixed bolt holes for easy installation

- Small board PCB size: 3.2cm×1.4cm

Adopts wide - voltage LM393 comparator

2. Wiring Instructions

- VCC: Connect to the positive pole of the power supply (3.3 - 5V)

- GND: Connect to the negative pole of the power supply

- D0: TTL switch signal output

- AO: Small board analog signal output (voltage signal)
