1. INTRODUCTION AND OVERVIEW
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 sun
light. The sensing distance can be adjusted manually. The product features include:
•
5V powered, low current consumption, less than 10mA.
•
3 pin interface which are signal, GND and 5V.
•
Small LED as indicator for detection status.
•
Obstacle detection up to 10cm.
•
Adjustable sensing range (2cm – 10cm).
•
Small size makes it easy to assembly.
•
Single bit output.
•
Compatible with all types of microcontrollers.
•
Dimension: 2.6cm x 2cm

3. PRODUCT SPECIFICATION AND LIMITATIONS
3.1 Theory of Operation
IR01A uses 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. The modulated
IR signal immunes the sensor from the interferences caused by the normal light of a light
bulb or the sun light. The module will output a HIGH if no object is detected and a LOW if
an object is detected.

3.3 Sensitivity
The Medium Range Infrared Sensor has a sensing range of approximately 2cm to 10cm. The
sensitivity can vary with the reflectivity of the object and the ambient lighting. The
modulated IR signal will reflect more on white surface and reflect less on black surface. The
sensor is designed to adjustable sensing range. User may adjust sensing range by using the
preset on IR01A for different application.

D – is a 1K Ohm preset for user to adjust the sensing range. The sensing range is 2cm –
10cm. (Performance of the sensor will vary with the reflectivity of the object and the ambient
lighting.)
E – is a hole to solder and connect the power supply to IR01A. User may supply 4V-6V to
IR01A, the typical voltage is 5V.
F – is a hole to solder and connect Ground to IR01A. User may connect the GND(-) of
IR01A to the Ground (0V) of the control board.
G – is a hole to solder and connect the output signal from IR01A. User may connect the
signal pin(s) from IR01A to an I/O pin of microcontroller which set to INPUT mode. The
output signal of IR01A is LOW or 0V when an object detected.

6. GETTING STARTED
Connect the 3-pin header to your circuit so that the VCC (+) pin connects to VCC (5V), the
Ground (-) pin connects to ground (0V) and the output signal (s) pin connects to your
microcontroller’s I/O pin. One easy way to do this would be to use a standard 3 ways 2561
connector. The output signal is LOW whenever there is an object detected.
Please refer following steps for example application of IR01A together with IFC-DI08
(Interface Free Controller – Digital Input Card).
1. Connect IR01A to IFC-DI08 as shown in Figure:
User needs to
connect IR01A to
IFC-DI08 follow
the label of the
pins (+ - s).
Ensure the
Voltage selected
as 5V.
Figure 6.1
Note: Ensure the pins from IR01A are connected correctly to IFC-DI08. Wrong
connection of IR01A will result improper function of IR01A and it might spoil the sensor
module.

2. Switch ON IFC, and test the IR01A, the indicator LED on IR01A should turn ON when an
object is proximity. User may adjust the sensing range by tuning the preset on IR01A. The
sensing range is 2cm -10cm, the performance of the sensor will vary with the reflectivity of
the object and the ambient lighting.
The indicator LED
on IR01A will turn
ON when an
object detected.
Figure 6.2

http://www.cytron.com.my/listProductCategory.asp?cid=285#3046
Note: When tuning the sensing range, please ensure there is not leakage IR signal from
the 2 IR transmitters. The indicator LED will always turn ON when there is leakage IR
signal detected on IR sensor even there is not object nearby. User need to re-tuning the
preset until there is not leakage IR signal from the module.
