Product Manual: Object Sensor Plug 

Introduction 

Object  Sensor  Plug  is  used  to  detect  the  obstacles  present  in  front  of  the  IR  sensors.  The  main  feature  of  this  plug  is  that  the  sensitivity  or  detection  range  can  be  adjusted  manually  to  meet  the consumer’s requirement. This plug can be  mounted anywhere using screws.   

   

Specification 

● Operating voltage: 5V  ● Size: 30mm x 30mm  ● Adjustable sensing range (1cm - 15cm) 

Variants  ● None

  Details 

Object  Sensor  Plug  consists  of  an  IR  transmitter  and  IR  receiver  with  amplifying  circuit  to  detect  the  obstacles  present  in  front  of  the  IR  sensors.  The  IR  transmitter  is  basically  an  IR  LED  that  emits  infrared  radiation.  The  IR  receiver  is  basically  a  photodiode  which  can  be  used  to  receive  the  IR radiations. It also has  a  POT  to  adjust  the  sensing  range,  approximately  1cm  to  15cm.  There  is  an  LED  on  the  board  which  indicates  the  obstacles  presence.  Whenever  the  IR  sensors  detect the obstacle LED turns ON.  There  is  a  slide  switch  to  select  the  modes  of  operation.  ‘A’  represents  the  Auto  mode  and ‘M’ represents the Manual mode. In the Auto mode the IR transmitter is  directly  connected  to  the  supply  so  that  IR  transmitter  always  emits  the  IR  radiations.  In  the  manual  mode  IR  transmitter  is  connected  to  the  T  pin  of  the  interfacing port so that the user can control the IR radiations..  Object  Sensor  plug  is  a  digital  input  device  to  the  interfacing  system.  It  has  an  interfacing  port  with  four  pins  named  as  G, V, R & T. Here G represents Ground, V  represents VCC, R & T represents receiver and transmitter data pins.    Note:  The  modulated  IR  signal  reflects more on white surface and reflect less on  black surface.   

How to interface? 

Use  either  of  the  supported interfacing cables to connect the Object Sensor Plug  to the controller board.  If  the  Object  Sensor  Plug is operated in the Auto mode then 3-3A or 4-3A cable is  prefered.  Since,  in  Auto  mode  T  pin  is  directly  pulled  HIGH  it  is  better  not  to  connect  plug’s  T  pin  to  the  data  pin  on  the  controller  board.  Using  3-3A  cable to  connect  the  plug  is  simple  as  last  pin  at  both  the  ports  are  left  unconnected.  If  4-3A  cable  is  to  be  used  then  3pin  end  of  the  cable  is  connected  to  the  object  sensor  plug  leaving  T  pin  and  4  pin  end  of  the  cable  must  be  connected  to  the  controller board.  If  the  Object  Sensor  Plug  is  operated  in  the  Manual  mode  then  4-4A  cable  is  prefered.  In  this  mode  the  user  provides  the  input  signal  to  the  T  pin of the plug.  While  using  4-4A  cable  any  end  of  the  cable  can  be  connected  to  the  object  sensor  plug.  Always  ensure  that  black wire of the cable is connected to the G pin  on  both  sides.  Make  sure  that  the  data  pins  of  the  object  sensor  plug  are  connected to the digital pins on the controller board.    The  table  given  below  shows  the  interfacing  of  object  sensor  plug  with  the  controller board using both 4-3A cable and 4-4A cable.    Elint Labz (​www.elintlabz.in​)

  In  the  below  given  picture  we  can  see  that  4-3A  cable  is  used  to  connect object  sensor  plug  which  is  configured  in  automatic  mode  to  the  pluguino  board.  The  receiver  data  pin  of  the object sensor plug (R) is connected to the digital pin  7 on  the controller board.    In  order  to  demonstrate  the  working  of the Object Sensor Plug we have used the  Buzzer  plug  to  indicate  whether  the  sensor  has  recognised  an  object  or  not.  Buzzer turns ON if the obstacle is detected.

Example Codes  Code 1: Arduino  #define Buzzer_pin 12 #define ObstaclePin 7 boolean isObstacle;

// buzzer plug is connected to 12th pin // object sensor plug is connected to 7th pin // variable to store the state of object sensor

void setup() { pinMode(ObstaclePin, INPUT); pinMode(Buzzer_pin, OUTPUT); }

// config 7th pin as an INPUT pin // config 12th pin as an OUTPUT pin

void loop() { isObstacle = digitalRead(ObstaclePin); // read the state of sensor and store if(isObstacle == LOW) // check whether obstacle is present { digitalWrite(Buzzer_pin, HIGH); // turn ON buzzer }
