About Project

E18-D80NK IR Obstacle Avoidance Proximity Sensor

The E18-D80NK is an IR Proximity Sensor with an obstacle detection range approx 3 cm to 80 cm. The utilization of modulated IR signal prevents the sensor from the interferences caused by the normal light of the sunlight. E18-D80 IR Sensor is generally utilized in robots to avoid obstacles. The detection range can be adjusted as per the application with the help of the multi-turn screw that is placed at the back of the sensor. For the connection of Interfacing of E18-D80NK IR Sensor with Arduino, attach the Brown wire of sensor with Arduino 5V pin, attach the Blue wire of sensor with Arduino’s Ground and attach Black pin of a sensor with a digital pin 7 of Arduino Nano.

Run a Program

const int e18_sensor = 7; const int led = 2; void setup() { Serial.begin(9600); pinMode (e18_sensor, INPUT); pinMode (led, INPUT); } void loop() { int state = digitalRead(e18_sensor); Serial.println(state); if(state==LOW){ Serial.println("Object Detected"); digitalWrite(led, HIGH); } else { Serial.println("All Clear"); digitalWrite(led, LOW); } delay(1000); }
