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)

4-3A cable (Automatic mode)
4-4A cable (Manual mode)
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 }
