Infrared Flame Sensor Module for Arduino – Light & Color Sensors
The Infrared Flame Sensor Module is a compact, plug‑and‑play board that detects the infrared radiation emitted by open flames and hot objects. Designed to stack directly onto any Arduino‑compatible board, it translates the invisible heat signature of a candle, stove, or Bunsen burner into a clean digital HIGH/LOW signal (and an analog voltage for fine‑tuned intensity reading). With its built‑in 5 V regulator and protective LED indicator, the sensor is ready for classroom labs the moment it arrives.
What students will learn:
- How infrared radiation differs from visible light and why flames are strong IR emitters.
- The fundamentals of analog‑to‑digital conversion, signal filtering, and threshold setting in microcontroller code.
- Real‑world safety monitoring concepts using sensors to detect fire hazards or control automatic extinguishing systems.
- Data‑driven design by logging flame intensity over time and visualizing trends with Arduino IDE or Python.
Key features
- Dual output: digital (TTL) and analog (0–5 V) for versatile projects.
- Adjustable sensitivity via on‑board potentiometer.
- Low power consumption (≈ 10 mA) and built‑in 5 V regulator for direct Arduino connection.
- Compact 20 mm × 15 mm footprint with mounting holes for breadboard or PCB integration.
- Robust housing with a transparent IR‑transparent window and protective LED status indicator.
Why it shines in STEAM education
This sensor bridges physics (infrared radiation, heat transfer), engineering (circuit design, embedded programming), art (visualizing flame intensity with LEDs or color‑changing displays), and mathematics (calibrating thresholds, analyzing sensor data). Its immediate, visible feedback, watch a candle’s flicker become a stream of numbers, engages curiosity and encourages iterative experimentation. By integrating the Infrared Flame Sensor into robotics, smart‑home, or environmental‑monitoring projects, students experience authentic, interdisciplinary problem‑solving that prepares them for the next generation of IoT and safety‑technology innovators.
