KY-026 – Infrared Flame Sensor Module (4 Pins)

⚡ Fast and Reliable Flame Detection
The KY-026 is a compact module designed to detect flames or infrared (IR) sources at short range. It provides both an analog output (AO) for precise readings and a digital output (DO) for simple triggering. Ideal for security, robotics, and embedded electronics projects.

🛡️ Functions & Protections

• 🔁 Immediate Detection: reacts quickly to flames or IR sources.
• ⚡ Digital Output: adjustable threshold via built-in potentiometer.
• 🔄 Analog Output: delivers a signal proportional to the IR intensity detected.
• 🧰 Easy Integration: compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers.

📦 Technical Specifications

• 🔌 Operating Voltage: 3.3V – 5V DC
• 🔋 Pins: VCC, GND, DO (Digital Output), AO (Analog Output)
• 🎯 Detection Range: up to 80 cm (depending on IR source)
• ⚙️ Sensitivity Adjustment: built-in potentiometer
• 📏 Dimensions: 32 mm x 14 mm x 10 mm
• 🌡️ Operating Temperature: -10°C to +50°C

🛠️ Applications

• 🔥 DIY flame and fire detectors
• 🤖 Surveillance or alarm robots
• 🏠 Home automation and security projects
• 📡 IoT systems requiring heat or IR light detection
• 🧪 Electronics prototyping and experimentation

⚠️ Usage Notes

• 🔌 Respect the recommended operating voltage (3.3V to 5V).
• ❗ Avoid exposing the sensor to intense IR sources for long periods to prevent saturation.
• 🔧 Adjust the potentiometer to calibrate the detection sensitivity for your application.
• ✨ Avoid nearby light interference (direct sunlight, strong IR LEDs).
