Yes, the command to get the reading in lux is “GRL”, as in “Get Reading in Lux”. Most commands start with either “S” (for setting parameters) or “G”, (for getting parameters or data).

So you would send over the serial port GRL<CR>. The meter will respond with grl nnn.nnn, where “nnn.nnn” is the measured light level in lux. Note that commands are not case sensitive. The Puck’s replies will always start with the command, so you know the command was accepted and that’s what it’s responding to.
