Hello everyone

I'm looking for sensors to fit into a device I'm planning
.

the sensor must be able to detect the presence of a pin of 10 mm diameter.

I was thinking about light emission sensors

that send a signal when the pin blocks the passage of light.


I would like to have some advice on the sensor type

the field of use:

temperatures ranging from -40 to 100 degrees centigrade

must be able to work even in rain conditions.

the minimum possible dimensions

duration of time

low energy consumption

power supply through photovolltaic energy.

economic

Could a solution result from the use of laser diodes that have 5 mm diameters?

Are there sensors with lower diameters?

Thank you for your cooperation.

But the pin is steel? In that case, maybe you'd better get an inductive, I think they're one of the most reliable.

I quote the two preceding me, especially on the inductive that is generally smaller, robust, reliable and economical than the optical ones. I can add:
