1. Introduction
The Grove - Flame Sensor can be used to detect fire source or other light sources of the
wavelength 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 firefighting robot game, the sensor plays a very important role, it can be
used as a robot eyes to find the fire source.

4. Usage
The module is mainly used to detect the infrared light. It outputs digital signal 0 and 1 through a
Comparator output. The output value will be 0 when infrared light is detected. And the sensitivity
is adjustable by the precision potentiometer.
Let's use it to control. When the output value is 0, the led will light up.
1. Connect the module to the D3 of Grove - Base Shield using the 4-pin grove cable.
2. Plug the Grove - Base Shield into Arduino.
3. Connect Arduino to PC by using a USB cable.
4. Copy and paste code below to a new Arduino sketch. Please click here if you do not know how
to upload.

}
boolean isFlameDetected()
{
if(digitalRead(FLAME_SENSOR))
return false;
else return true;
}
5. The LED will light up when there is infrared light. Please use it to design your products.
