Grove - Flame Sensor
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 fire fighting robot game, the sensor plays a very important role, it can be used as a robot eyes to find the fire source.
Features
- Grove Interface
- High Photo Sensitivity
- Fast Response Time
- Easy to use
- Sensitivity is adjustable

The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.
Getting started
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.

Hardware
- Step 1. Prepare the below stuffs:
| Seeeduino V4.2 | Base Shield | Grove-Flame_Sensor | Grove - Red LED |
|---|---|---|---|
 |  |  |  |
| Get One Now | Get One Now | Get One Now | Get One Now |
- Step 2. Connect Grove-Flame_Sensor to port D2 of Grove-Base Shield.
- Step 3. Connect Grove - Red LED to port D3 of Grove-Base Shield.
- Step 4. Plug Grove - Base Shield into Seeeduino.
- Step 5. Connect Seeeduino to PC via a USB cable.
If we don't have Grove Base Shield, We also can directly connect this module to Seeeduino as below.
| Seeeduino | Grove-Flame_Sensor |
|---|---|
| 5V | Red |
| GND | Black |
| Not Conencted | White |
| D2 | Yellow |
| Seeeduino | Grove - Red LED |
|---|---|
| 5V | Red |
| GND | Black |
| Not Conencted | White |
| D3 | Yellow |
Software
Step 1. Copy the code and flash it into the controller board.
Here is the code
/******************************************************************************/
#define FLAME_SENSOR 2 //connect SENSOR to digital pin2
#define LED 3 //connect Grove - LED to pin3
void setup()
{
pinsInit();
}
void loop()
{
if(isFlameDetected())
turnOnLED();
else turnOffLED();
}
/********************************/
void pinsInit()
{
pinMode(FLAME_SENSOR, INPUT);
pinMode(LED,OUTPUT);
digitalWrite(LED,LOW);
}
void turnOnLED()
{
digitalWrite(LED,HIGH);
}
void turnOffLED()
{
digitalWrite(LED,LOW);
}
boolean isFlameDetected()
{
if(digitalRead(FLAME_SENSOR))
return false;
else return true;
}
Step 2. The LED will light up when there is infrared light.
Play with Codecraft
Hardware
Step 1. Connect a Grove - Flame Sensor to port D2, and connect a Grove - Red LED to port D3 of a Base Shield.
Step 2. Plug the Base Shield to your Seeeduino/Arduino.
Step 3. Link Seeeduino/Arduino to your PC via an USB cable.
Software
Step 1. Open Codecraft, add Arduino support, and drag a main procedure to working area.
If this is your first time using Codecraft, see also Guide for Codecraft using Arduino.
Step 2. Drag blocks as picture below or open the cdc file which can be downloaded at the end of this page.
Upload the program to your Arduino/Seeeduino.
When the code finishes uploaded, the LED will goes on when Flame Sensor detects flame.
Play With Raspberry Pi
Hardware
- Step 1. Prepare the below stuffs:
