This Medium Range Infrared sensor offers simple, user-friendly and fast obstacle detection using infrared; it is non-contact detection. The implementations of modulated IR signal immune the sensor to the interferences caused by the normal light of a light bulb or the sunlight. The sensing distance can be adjusted manually.
IR01A uses a special sensor to modulate IR signal emitted from 2 IR transmitters and detects the modulated IR signal reflected back from a nearby object. This sensor has a built-in IR LED driver to modulate the IR signal at 38KHz to match the built-in detector. This modulated IR signal immunes the sensor from the interferences caused by the normal light of a light bulb or the sunlight and will give HIGH output if no object is detected and a LOW if an object is detected.
This tutorial will show you how to operate this sensor using Maker UNO.
SPECIFICATION

- 3 pin interface which is signal, GND and 5V.
- Small LED as an indicator of detection status.
- Obstacle detection up to 8cm.
- Adjustable sensing range (2cm – 8cm).
- Small size makes it easy to assemble.
- Single bit output.
- Compatible with all types of microcontrollers.
- Dimension: 2.6cm x 2cm
HARDWARE REQUIREMENT
- 1 x Medium Range Infrared Sensor
- 1 x Right Angle Pin Header (Male) 1×40 Ways
- 3 x Male to Female Jumper Wire
- 1 x Maker UNO -Arduino UNO Compatible
- 1 x USB Micro B Cable
SOFTWARE REQUIREMENT
STEPS
- Solder Right Angle Pin Header (Male) to the IR01A hole.
2. Build circuit as in the schematics :
3. Sketch the following code in the Arduino IDE :
/*Created on 4/5/2018 by Cytron Technologies
*IR01A - Medium Range Infrared Sensor
*Product page - https://www.cytron.io/p-ir01a
*/
int IR_pin = A0; //Set IR pin to pin A0 of MakerUNO
void setup() {
pinMode(IR_pin, INPUT); //Set IR_pin as INPUT
Serial.begin (9600); //Communication baud rate use 9600
}
void loop() {
int IR_Reading = digitalRead (IR_pin); //Get the reading input for the IR01A
Serial.print(" IR Reading = "); //Print the IR Reading on Serial Monitor
Serial.println(IR_Reading); //Print the value of IR Reading
}
4. Upload the code and enjoy it!
