Introduction

Interfacing KY-026 Flame Sensor module with Arduino, The KY-026 Flame Sensor module is an essential component in fire detection and prevention systems. This module can detect the presence of a flame or fire source and trigger an alarm or warning signal to alert users to the danger. It is a highly reliable and accurate sensor that is widely used in various fields, such as home appliances, industrial automation, and aerospace.

This module is compatible with popular electronic platforms like Arduino, ESP32, Raspberry Pi, and other microcontrollers. which utilize an infrared receiver to detect the presence of a flame or fire source.

Hardware Required

You will require the following Hardware Components for interfacing the KY-026 Flame Sensor module with Arduino.

What is the KY-026 Flame Sensor module?

The KY-026 Flame Sensor module is an electronic component that uses an infrared receiver to detect the presence of a flame or fire source. It is composed of an infrared receiver, a potentiometer, and a comparator IC. When a flame is present, the infrared receiver will receive a signal, which will be compared to the threshold set by the potentiometer. If the signal exceeds the threshold, the comparator IC will trigger an output signal.

Specifications

The module is composed of several components including a 5mm infra-red receiver LED, an LM393 dual differential comparator, a 3296W trimmer potentiometer, six resistors, two indicator LEDs, and four male header pins. The board features a digital and analog output.

Features

1. High sensitivity to flames and fire sources
2. Quick response time
3. Adjustable detection threshold
4. Low power consumption
5. Easy to integrate with other electronic components
