This Flame Sensor can be used to detect fire source or other light sources of the wave length in the range of 760nm – 1100 nm. It is based on the YG1006 sensor which is a high speed and high sensitive NPN silicon phototransistor. Due to its black epoxy, the sensor is sensitive to infrared radiation. In fire fighting robot game, the sensor plays a very important role, it can be used as a robot eyes to find the fire source.
When detected the flame the Signal LED will on and the D0 output LOW voltage level.
Features
- High Photo Sensitivity
- Fast Response Time

Specification
- Working voltage: 3.3v-5v
- Detect range: 60 degrees
- Digital/Analog output
- On-board LM393 chip
- Dimension of the board: 3.2cm x 1.4cm
