Questions about this product
- What's the detection range and can I change it?
- It has an adjustable detection range from 3cm up to 80cm. You can adjust the distance using the multi-turn potentiometer on the back of the sensor. The sensor itself is 17mm in diameter and 45mm long.
- Will this work with an Arduino for a robot project?
- Yes, it's commonly used with microcontrollers like Arduino. It runs on 5V DC and has a simple switching output, making it straightforward to connect to the digital input pins on your board.
- What kind of objects will this sensor actually detect?
- This is an infrared photoelectric sensor, so it detects objects by bouncing a beam of infrared light off them. It works well with solid, opaque objects but may struggle with transparent, black, or very thin surfaces that don't reflect the light back properly.
