1. INTRODUCTION AND OVERVIEW
This Digital Infrared Sensor offers simple, user friendly and fast obstacle detection using
infrared. This is an Digital Infrared Sensor. This product is used during the reflection of IR
by obstacles. It is widely to use in various type of industry such as spinning and weaving,
mechanical, iron and steel, chemical,electric power, security and so on.This product features
include:
Figure 1.1 The reflection of Digital Infrared Sensor on the object
●Cylindrical, diffuse reflectance
●*NPN output
●Three-wire.
● **6V-36V powered, low current consumption, less than 300mA.
●***Obstacle detection up to 30cm.
● Adjustable sensing range (0cm-30cm).
●Small size makes it easy to assembly.
●High precision, waterproof, protect corrosion, resist of light.
●Widely useful for robot,interactive media,industrial assembly,etc.
* Though it is NPN output, but internally it is being pull up the power pin.
** Test show it can be powered as low as 5V.
*** Longer distance can be achieve if power voltage is increase.

3. PRODUCT SPECIFICATION AND LIMITATIONS
3.1 Theory of Operation
The SN-E18-B03N1 contains infrared sensor for use as reflection of IR signal barriers. It
uses special sensor to detect the modulated IR signal reflected back from a nearby either or
a far distance of the object. The transmitter and the receiver between the light intensity of the
digital infrared sensor can change into for the purpose of current changes in order to achieve
the detection. The output signal of Digital Infrared Sensor is needed to be pull high as it is
NPN output. The module will output a HIGH if no object is detected and a LOW if an object
is detected.
Note: Although the specification stated it is NPN output, we notice the sensor itself is
being pull-up internally. Causing the output pin is being pull up to power pin. So if 12V is
supply, you will get ~12V at output when no obstacle is detected.

3.3 Sensitivity
The Digital Infrared Sensor has a sensing range of approximately 0cm to 30m for a white or
shiny color object. For a dark or black color object, the Digital Infrared Sensor has a sensing
range of approximately 2cm to25cm. It shows that the sensor will reflect more on a white
surface than a black surface. The sensor is designed to adjustable sensing range.When user
adjust the white preset (at the bottom of Digital Infrared Sensor, the range object detected
also change. If user adjust the preset to counter-clockwise, the detected range will less than
30cm. The more user adjust the preset to counter clockwise, the more short the Digital
Infrared sensor may detect object.
3.4 Test Result in Lab
We have tested the sensor in our lab with different voltage and here is the result.
Voltage, V Maximum detectable distance (obstacle)
5V 20cm
12V 60cm
30V 80cm
All test is using Cytron’s packaging white color box as obstacle. Other object might have
different result as it depends on the reflective of Infrared of object surface. The above result
is just for reference.

A- User may supply 6V-36V to SN-E18-B03N1, the typical voltage is 12V.
B-User may connect the GND (-) of SN-E18-B03N1 to the Ground (0V) of he control board.
C-User may connect output signal to an I/O pin of microcontroller which set to INPUT mode.
The output signal of Digital Infrared Sensor is needed to be pull high as it is NPN output. The
module will output a HIGH if no object is detected and a LOW if an object is detected.

5. GETTING STARTED
5.1 Connecting and Testing
Example 4.1 Example interface for Digital Infrared Sensor ( With SK40C), using LC04A as
level shifter.
Part Description
Digital Infrared Sensor
Connector
Connects to Digital Infrared Sensor, pin 1 to output (Black
Color),pin 2 to GND (Blue color) and pin 3 to Vcc (Brown
color)
Vcc Connects to Vcc (+6V to +36V), 5V is possible too.

SK40C The output of sensor is shifted to logic 5V via LC04A and go
into RB0 of SK40C. RB0 is input of SK40C.
The interface of Digital Infrared Sensor is shown in Figure 4.1, with reference to the
schematic , the output signal which sends to microcontroller with LOW wherever there is a
infrared detected and high if no object detect.
