Good daylight sensor for outdoor monitoring

I put this daylight sensor on a small weather monitoring setup outside. Finding a good spot took a little trial and error because I didn’t want the nearby structure blocking the light. I’m using RS485 to get the readings back to the controller. Had to check the readings a few times after mounting it, but everything has been looking good so far.
