The KY-032 Infrared Sensor

The KY-032 Infrared Sensor is a module that is commonly used in electronics and robotics projects for detecting the presence of infrared signals. It is also known as an infrared obstacle avoidance sensor module. The module consists of an infrared emitter (LED) and an infrared receiver (phototransistor) placed side by side.

Here are some key features and characteristics of the KY-032 Infrared Sensor:

1- Detection Method: The sensor module detects infrared light by emitting a modulated infrared signal and measuring the reflection. When an object is present in front of the module, the infrared light emitted by the LED bounces off the object and is detected by the phototransistor.

2- Operating Voltage: The KY-032 module typically operates at a voltage range of 3.3V to 5V, making it compatible with most microcontrollers and development boards.

3- Digital Output: The module provides a digital output that can be easily interfaced with microcontrollers or other digital circuits. It produces a HIGH (logic 1) output when no obstacle is detected and a LOW (logic 0) output when an obstacle is detected within its detection range.

4- Adjustable Detection Range: The detection range of the KY-032 sensor can be adjusted using a potentiometer on the module. This allows you to fine-tune the sensitivity of the sensor according to your specific requirements.

5- Applications: The KY-032 Infrared Sensor can be used in various applications, including obstacle detection and avoidance in robotics, line following robots, proximity sensing, object detection, and security systems.

When using the KY-032 Infrared Sensor, it's important to keep in mind that it primarily detects the presence of objects based on their reflective properties rather than their distance. The effectiveness of the sensor can be affected by factors such as ambient light and the reflective properties of the objects being detected.

The components needed to use the KY-032 infrared sensor, two lamps and two relays with the Arduino UNO

To use the KY-032 infrared sensor, two lamps and two relays with the Arduin UNO, you will need a few components and connections. Here's a list of the required items:

Arduino UNO board:

Arduino Uno

The Arduino UNO board is a popular microcontroller board based on the ATmega328P microcontroller. It is one of the most commonly used Arduino boards and provides a versatile platform for creating interactive electronic projects.

The Arduino UNO board is suitable for beginners and experienced users alike, offering a flexible and accessible platform for prototyping and building various electronic projects, from simple LED blinking to complex robotics and home automation systems.

Two relays Modules:

Two relays

A relay module is an electronic device used to control high-power circuits with low-power signals. It consists of a relay, which is essentially an electromagnetically operated switch, and typically includes additional components like transistors, diodes, and optocouplers for protection and isolation.

You'll need a relay module that is compatible with the Arduino UNO and can switch the high-voltage lamp. Ensure it's rated for the voltage and current required for your lamp.

Two lamps (220V):

Power Supply for the Lamp:

You'll need a power source for the lamp, typically a 220V AC power supply.

Wiring:

Various wires and cables for connecting the components in your circuit.

Breadboard:

Arduino UNO programming of the Arduino UNO to receive data from the KY-032 infrared sensor and light up Two lamps

To program the Arduino UNO board to receive data from the KY-032 infrared sensor and light up a lamp, use the following code as a starting point for your Arduino sketch:

1- Download and install the IRremote library in your Arduino development environment. This library will enable you to receive and decode infrared signals.

- Open the Arduino IDE on your computer.

- Go to "Sketch" -> "Include Library" -> "Manage Libraries".

- Search for "IRremote" in the search box.

- Select the "IRremote" library

- Click "Install" to install the library.

2- In the Arduino IDE, create a new sketch and use the following code as a starting point:

#include <IRremote.h>

int IR_RECEIVE_PIN = 4; // Use the same pin that you connected to the OUT pin of the KY-032 sensor
int relay_lamp1 = 2; // Use the pin to connect arduino to relay 1 
int relay_lamp2 = 3; // Use the pin to connect arduino to relay 2

IRrecv irrecv(IR_RECEIVE_PIN);
decode_results results;

void setup()
{
  Serial.begin(9600);
  pinMode(relay_lamp1, OUTPUT);
  pinMode(relay_lamp2, OUTPUT);
  irrecv.enableIRIn(); // Enable infrared reception
}

void loop()
{
  if (irrecv.decode(&results))
  {
    unsigned long value = results.value;
    Serial.println(value, HEX); // Print the received infrared code in hexadecimal format
    irrecv.resume(); // Prepare the sensor to receive the next infrared signal

    // Example: Turn on the lamp when a specific infrared code is received
    if (value == 0xFF30CF) // press button 1 on your remote control
    {
      digitalWrite(relay_lamp1, HIGH); // Turn on the lamp 1 by the relay 1
      digitalWrite(relay_lamp2, LOW); // Turn off the lamp 2 by the relay 2
    }
     if (value == 0xFF18E7) // press button 2 on your remote control
    {
      digitalWrite(relay_lamp1, LOW); // Turn off the lamp 1 by the relay 1
      digitalWrite(relay_lamp2, HIGH); // Turn on the lamp 2 by the relay 2
    }
  }
}
