The E18-D80NK sensor is used to detect obstacles and objects. This sensor works based on transmitting infrared rays. First, the transmitter sends the rays in a direct path. This ray hits the obstacle and returns to the receiver. There is a potentiometer on this module that can be adjusted to change this detection distance from 3 to 80cm. In fact, with this sensor, the obstacle can be detected, but the distance cannot be calculated directly. There is also an LED on this sensor that turns off by detecting an obstacle. When there is an obstacle, the sensor output is HIGH, otherwise it is LOW.
This sensor is used in robotics, parking sensor, RPM counting, etc.
Note:
- If you turn the potentiometer clockwise, the detection distance will increase and vice versa.
- As this is an infra-red sensor it can be affected external sources of infra-red light such as sunlight.
Maximum range will be affected by environmental conditions and reflectiveness of sensed object

This Module has 3 Wires:
- VCC: Module power supply – 5V (Brown)
- GND: Ground (Blue)
- OUT: Digital output (Black)
Setup instructions:
With nothing is obstructing the sensor, adjust the multi-turn screw at rear of sensor until the LED switches from off to on. The sensor should then be calibrated for its current environment.
