KY-026 Flame Sensor Module Fire Source Detection

The KY-026 Flame Sensor Module is a high-sensitivity infrared receiver module designed to detect fire sources and light wavelengths ranging from 760 nm to 1100 nm. Powered by the highly reliable LM393 comparator IC, this module provides both analog and digital outputs, making it incredibly easy to interface with various microcontrollers. It is a critical safety component for fire alarms, smart firefighting robots, and industrial monitoring systems.

This module features an onboard multi-turn potentiometer that allows users to adjust the detection sensitivity to suit specific environmental conditions. The digital output (DO) delivers a clean high/low signal when a flame is detected, while the analog output (AO) provides a real-time voltage level proportional to the flame intensity. Fully compatible with Arduino, ESP32, Raspberry Pi, and other development boards, the KY-026 is an essential addition to any maker's toolkit for building automated safety projects.

Features:

• Dual Output Mode: Provides both digital (DO) switch output and analog (AO) voltage output for precise measurements.
• High Sensitivity: Specifically tuned to detect infrared light wavelengths from 760 nm to 1100 nm, typical of open flames.
• Adjustable Threshold: Onboard multi-turn potentiometer allows easy calibration of the digital trigger point.
• Integrated LM393 Comparator: Ensures stable signal processing, low noise, and a clean digital waveform output.
• LED Indicators: Features onboard power and status LEDs for quick visual debugging and operation verification.
• Easy Mounting: Includes a pre-drilled bolt hole for secure installation on smart car chassis or sensor brackets.
