KY-026 Flame Sensor Module | Infrared (760-1100nm) Fire Detection Module with Adjustable Sensitivity Potentiometer for Arduino, Raspberry Pi and Embedded Fire Safety / Robotics Detection Projects
Ensure fire safety with the KY-026 Flame Sensor Module designed for fire detection applications. This sensor operates in the infrared spectrum from 760 nm to 1100 nm — the wavelength range characteristic of open flame emissions — offering precise flame detection capabilities. Featuring an adjustable switching contact with potentiometer, this module is compatible with Arduino and Raspberry Pi platforms, making it versatile for various projects requiring fire detection functionality.
Typical Applications
- DIY fire alarm projects — embedded fire detection in custom safety systems.
- Robotics fire response — autonomous fire-fighting robots, flame-avoidance navigation.
- Smart home safety — supplementary fire detection alongside standard smoke alarms.
- Educational electronics — teaching IR sensing, threshold detection, alarm logic.
- Industrial process monitoring — flame detection in flame-based industrial processes.
- Microcontroller integration — Arduino / STM32 / ESP32 / Raspberry Pi-based fire-triggered logic.

FAQ — KY-026 Flame Sensor
Q: What's the detection range / angle?
A: The KY-026 detects flames within a cone roughly 60° forward from the sensor face, at distances typically 0.5-1 meter for a small candle flame. Larger flames are detectable at greater distances. The adjustable potentiometer lets you tune sensitivity to your specific use case.
Q: Will sunlight cause false triggers?
A: Direct sunlight contains broad IR spectrum including the 760-1100nm band — possible false trigger. Mount the sensor away from direct sun exposure. For outdoor use, use a hood / shade or supplement with additional sensing (UV flame detector, smoke sensor) for false-trigger rejection.
Q: Can I use it for commercial fire detection?
A: No — the KY-026 is suitable for hobbyist, educational, and indicative monitoring. For commercial / industrial / life-safety fire detection, use certified fire detectors with regulatory approval (UL, CE-rated). Treat KY-026 detection as informational, not safety-grade.
Q: Bulk pricing for production runs?
A: Yes — email contact@lys-sz.com with your quantity for tier pricing on educational kits or production deployments.
