Hello,
I'm working on a project where I have to detect sparks from a generator. I need to know how big and where the sparks are. I'm planning to use an Arduino Due for this. What type of sensor should I use?
Thank you.
A camera with a UV pass filter?
Without knowing exact details of the setup (size, obstacles, external light, locating precision requirements, ...) I think it could possibly be done with 3 or 4 photodiodes and basic triangulation algorithm taking light intensity signal as distance and more or less calibration (depending if you need relative spark size difference or absolute).
Again, lots of ifs not specified so... take this with grain of salt or give more details.
IR camera or look for flame sensor. it detects a specific ir frequency that is emmitted when a flame is present. cant imagine size or positions without a ir camera

A generator uses a commutator and brushes. They always spark when under electrical load. More load, more sparks. That is why brushes need to be replaced periodically. And the commutator cleaned and possibly turned down.
I would use, as suggested, some type of photo cell if the area around the brushes can be made dark.

Sparks let off UV. UV sensors is one way to detect the sparks. I'm currently working with UV TRON sensors.
