E18-D80NK is an infrared proximity sensor that detects objects from a distance. It comes with a long detection range of 3 to 80cm. A unique feature of the sensor is that it allows you to adjust the detecting range (sensitivity) with a simple screwdriver turns.
The sensor is an excellent choice for projects that make use of objects and obstacle detection, collision avoidance and many more can be made by using it with microcontrollers like Arduino and Raspberry Pi. E18-D80NK does not measure distance but still gives a digital output on detection.
The E18-D80NK sensor is small, cheap and easy to use. It has a small size compared to the distance it can cover. The sensor specifications are listed below:
- Diameter: 18mm
- Length: 45 mm
- Sensing range: 3 - 80 cm adjustable
