Data Sheet

1 Introduction
The flame sensor is used to detect the presence of fire or other infrared source (Flame or a light source of a
wavelength in the range of 760 nm to 1100 nm can be detected). It can be used in fire fighting robot or heat
seeking robot.
2 Features
 Small and compact in size
 Adjustable threshold value
 2 state binary output (logic high and low)
 Easy mounting with a screw hole.
3 Specifications
 Input operating voltage: 5V
 Logic high level: supply voltage (5V)
 Logic low level: 0V
4 Hardware Connections
The module has simple 3 pin male berg connector having Vcc, ground and output pin. The potentiometer is
provided to adjust the threshold level. To read sensor status D0 pin should be connected to a GPIO pin. Figure
1 below shows the pin layout for flame sensor.

5 Pseudo Code
boolean flameGetStatus(void)
{
// read D0 pin status
if(gpioReadPin(D0) == 1)
return true; // flame detected
else
return false; // no flame detected
}
