Brief Introduction

1. Can detect flames or light sources with wavelengths ranging from 760 nanometers to 1100 nanometers. The lighter tests flames at a distance of 80cm, and the larger the flame, the farther the test distance

2. Detection angle of around 60 degrees, particularly sensitive to flame spectra

3. Sensitivity adjustable (blue digital potentiometer adjustment in the figure)

4. The comparator output signal is clean with good waveform and strong driving capability exceeding 15mA

5. Equipped with adjustable precision potentiometer to adjust sensitivity

6. Working voltage: 3.3V-5V

7. Output format: D digital switch output (0 and 1) and A0 analog voltage output H

8. Equipped with fixed bolt holes for easy installation

9. Using a wide voltage LM393 comparator

Instructions

1. Flame sensors are sensitive to flames and also have a response to ordinary ones. They are generally used for flame alarm and other purposes

2. The output interface of the small board can be directly connected to the I0 port of the microcontroller

3. The sensor should be kept at a certain distance from the flame to avoid damage from high temperatures. The flame distance for testing lighters is 80cm, and the larger the flame, the farther the test distance

4. Small board analog output method and AD conversion processing can achieve higher accuracy
