Laser Detection Sensor
<p><br />
I have been trying to work on a project that requires me to know when a laser is being hit into a sensor. Unfortunately, I am not able to find such a product that gives an output current when it is hit by a laser to be used with a Raspberry Pi/Arduino. I heard of Laser Break Beam Sensors, but I do not want to purchase the wrong thing.</p>

<p>Would anyone know of a sensor of sorts? And possibly a controllable laser to go with?</p>

<p>Thanks.</p>

<p>Look into a standard LED. They can produce a current when hit with a laser. Or a small solar panel might work better. You can then interpret this using a python script and GPIO from the Raspberry Pi. The laser can also be wired from a GPIO and controlled from software.</p>
