General purpose NPN output infrared sensor that offered up to 30cm sensing distance. It can be used at automation machine, mobile robot for obstacle detecting. it is a 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.

Specification:
  • Diffuse reflective type
  • Light source: Infrared
  • Sensing range up to 30cm
  • Input voltage: 6-36VDC
  • NPN output

Dimension: 1.6cm (D) x 6.7cm (L)

Result from test:
  • 5V can be use to power, maximum dectection distance is ~20cm
  • 12V, maximum dectection distance is ~ 60cm
  • 30V, maximum dectection distance is ~ 80cm
  • All above test is using Cytron’s white box as obstacle, in our lab.

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:

  • 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.

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. 

3.2 Pin Definitions and Ratings

Color   Name Function
Brown VCC Connects to VCC (+6V to +36V)
Blue Ground Connects to Ground
Black Output Signal Connect to an I/O pin of microcontroller which set to INPUT mode

Absolute Maximum Rating 

Parameter Min Max Unit
Operating voltage 6 36 V
Sensing meter 0 30 cm

 

Lab test result show even as low as 5V the sensor can still function. Yet, we do no test for all sensor. 

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 to 25cm. 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.

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. 

 

Label Function
A Connect VCC(+)
B Connect GND(-)
C Connect Output Signal (S)

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. 

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.
