Laser detection

Hello, I need advice on finding an optical sensor that can detect a small laser, and provide feedback of detection to Arduino please.



A phototransistor may be useful. Look for one with a wavelength similar to that of the light source you’re trying to detect, noting that any ambient light in the chosen sensor’s range of sensitivity will be a source of interference with which you’ll need to contend.

Also, this is a recent post that may prove enlightening.
