IR Flame Sensor Module

A flame sensor module that consists of a flame sensor (IR receiver), resistor, capacitor, potentiometer, and comparator LM393 in an integrated circuit. It can detect infrared light with a wavelength ranging from 700nm to 1000nm.The far-infrared flame probe converts the light detected in the form of infrared light into current changes. Sensitivity is adjusted through the onboard variable resistor with a detection angle of 60 degrees.

Working voltage is between 3.3v and 5.2v DC, with a digital output to indicate the presence of a signal. Sensing is conditioned by an LM393 comparator. 

Flame Sensor Module Connection Details

Connecting your Flame Detector to an Arduino

Auduino to Flame Sensor Connections


A very simple Arduino Sketch is shown below, and assumes you have an LED connected to Pin 13 to indicate when a flame has been detected.

// Flame Sensor Module

int LED = 13; // Use the onboard Uno LED
int isFlamePin = 7;  // This is our input pin
int isFlame = HIGH;  // HIGH MEANS NO FLAME

void setup() {
  pinMode(LED, OUTPUT);
  pinMode(isFlamePin, INPUT);

void loop() {
  isFlame = digitalRead(isFlamePin);
  if (isFlame== LOW)
    Serial.println("FLAME, FLAME, FLAME");
    digitalWrite(LED, HIGH);
    Serial.println("no flame");
    digitalWrite(LED, LOW);


Verify Operation of the Flame Detector Module and Adjust Sensitivity

Open the Serial Monitor on your Arduino program.  Move a flame in and out of the viewing angle of the sensor.  You should see an output that looks something like the picture below.   You should also see the red LED illuminate on your module and you should see also see the module LED connected to pin 13 of your Arduino light up.

TCS3200 Color Sensor Module

The TCS3200 is a color sensor which has an array of photodiodes. To detect color, the photodiodes are arranged in groups of four with red, green, or blue filters on three of the photodiodes and no filter on the fourth. This allows the sensor to measure the amount of red, green, blue, and white light that hits the sensor.

This module incorporates four white LEDs to illuminate an object of which you wish to measure the color of. The white light from these LEDs hits your test object and reflects back to the module's sensor, which then measures the amount of red, green, blue, and white light that was reflected.

As is, this module is susceptible to ambient light. We recommend creating a shroud to keep ambient light out of the test area or use the sensor in a dark area with little ambient light to get better results.

This module does fit on a standard breadboard, but it spans the width of the standard prototyping pins, requiring connecting wires to be connected to the breadboard under the module.

IR Proximity Sensor Module Obstacle Avoidance
Detects the proximity of an object by means of infrared light. The sensitivity can be adjusted with the potentiometer on the module. Works on 3.3V to 5V. The output D0 is low if the reflection value of the infrared light falls below the threshold value, and high if it falls above the threshold value.
LDR Light Sensor Module
This module senses the light and gives an output, The sensitivity of output can be set using a pot. Both digital and analog outputs are available.
