If using, you can also set up the Vernier light meters (either at individual stations or as one or two optional tools for groups who want it).

The light meter connects to a Lab Quest Mini. Open Logger Pro, and the software will auto-detect the sensor. A live reading is available in the lower left corner of the screen.

Note that the chip on the end of the stick is the light-sensitive part (not the glass tube). Also note that the sensor has an adjustable range switch; students should change this as needed.
