This E18-D80NK is an infrared sensor for obstacle avoidance in DIY electronics. It sends out an infrared beam to find objects from 3 to 80 cm away. This helps your smart car or robot move around without hitting things. You can easily set the detection range. Features and Benefits
- Adjustable 3-80 cm detection range - You can fine-tune how far it looks for objects, good for different robot speeds and places.
- NPN open-collector output - Sends a simple digital signal to microcontrollers like an Arduino.
- Onboard indicator light - It turns on when it sees an object, which makes testing and fixing your project easier.
- Infrared photoelectric technology - It works by sending and receiving light. This means the color of the object it detects doesn't matter. Applications
- Building a smart car robot that can automatically drive around walls and furniture.
- Making an automated system on a small assembly line to know when a part is in place.
- Designing interactive art or displays that react when someone gets close.
What It Is
This Sensor Switch is an E18-D80NK Proximity Detector, designed to sense objects within a specific range without physical contact. It operates using a photoelectric detection method, meaning it uses light to detect the presence or absence of an object. This particular model is an infrared obstacle avoidance sensor, functioning as an optical sensor. It is an electronics module that provides a digital output when an object is detected.
Key Uses & Applications
This proximity sensor is suitable for various applications requiring non-contact detection. Its adjustable detection range, from 3 cm to 80 cm, makes it versatile for tasks such as automated gate control, object counting on a conveyor belt, or robotics for obstacle avoidance. As an industrial sensor, it can be integrated into systems where a reliable digital signal is needed to indicate an object's presence. The 5V operating voltage ensures compatibility with common electronics.
How to Choose
When selecting a proximity sensor, consider the required detection range; this model offers 3 cm to 80 cm. Evaluate the operating voltage, with this sensor requiring 5V. The output type, in this case digital, is crucial for integration with your control system. For testing a proximity sensor like this, you would typically apply the specified operating voltage and then pass an object through its detection field, observing the digital output change. Consider if a barrel sensor form factor is suitable for your mounting requirements.

Product Name: Smart Car Robot E18-D80NK Infrared Obstacle Avoidance Photoelectric Sensor Proximity Switch. Response Time: Less than 2 ms. Sensor Type: Infrared Photoelectric Sensor. Theory: Optical Sensor. Q: What is the detection range on this sensor, and can I adjust it? A: It detects objects between 3 and 80 cm away. You can change the sensing distance by turning the small screw on the back, which lets you fine-tune it for your specific robot or project.. Q: How does it perform in a room with bright lights? Will that cause false readings? A: This sensor uses modulated infrared light, so it's much less likely to be affected by sunlight or normal indoor lighting. It's designed to distinguish its own signal from ambient light for more reliable operation.. Q: Can I hook this up directly to an Arduino or Raspberry Pi? A: Yes, it's straightforward to connect. It has a 3-wire interface for power, ground, and a digital signal output that you can connect right to a GPIO pin on most microcontrollers.. Q: I need to detect clear plastic. Is this an infrared sensor or a capacitive sensor? A: This is a photoelectric infrared (IR) sensor, not a capacitive sensor. It works by detecting reflected light, so it will reliably detect most opaque or solid objects, but may have trouble with transparent materials.. Q: What's included in the package? Is it just the sensor itself? A: You get the E18-D80NK sensor module itself. It's a single, self-contained unit with the transmitter and receiver built in, ready to be wired into your project..
