Measure Light and Optical Changes with a Compact Sensor
The Flame Sensor for Arduino is a light sensor with uart designed for light logging, optical switching, line tracking, and brightness-aware projects. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds.
Key details include Supply voltage: 3.3 V to 5 V DC; Two outputs: use D0 (LM393 comparator) for on/off alarms, or A0 to read intensity via ADC.; Interface pins: VCC, GND, D0, A0.
Why you’ll love it
- Flame sensor module (Analog + Digital): Flame sensor module (Analog + Digital)
- Useful spec: IR flame sensor (photodiode/phototransistor tuned to ~760–1100 nm)
- Sensing range: Up to ~80–100 cm for a lighter flame in dim light ( depends on flame size & ambient IR )
- Easy wiring: VCC, GND, D0, A0
- Power range: 3.3 V to 5 V DC
- Compact size: Small module; fits breadboards and mini project boxes (dimensions vary slightly by batch)

Frequently Asked Questions
What does the Flame Sensor for Arduino measure?
It is designed to measure light, color, or optical changes.
Can I use it with Arduino, ESP32, or Raspberry Pi?
Yes. It is well suited for common maker and embedded platforms, as long as you power it at the correct voltage and match the signal level to your controller.
How do I connect this UART sensor?
This version uses UART or serial output, so you connect power plus TX and RX at the correct logic level.
What affects accuracy?
Power quality, wiring, mounting, target material, and the real environment can all affect the reading. It is best to test and calibrate in the final setup.
Is it good for prototyping?
Yes. It is a practical choice for learning, proof-of-concept builds, and small automation projects.
