+ What is the difference between a PAR Sensor and Quantum Sensor?
+ What is the advantage in using the LI-191R Line Quantum Sensor vs. the LI-190R Quantum Sensor?
+ How many light sensors can connect to the LI-1500 datalogger at one time?
+ How many sensors can I connect to the LI-250A light meter?
+ What are the differences between the BNC, BL, and SMV sensors?
+ Do LI-COR sensors require external power?
+ I need to measure how much light my experimental plants are receiving. Which type of sensor should I use?
+ I'm working on a smart building that opens and closes window shades based on the internal light levels. Which sensor would be best for this?
+ I'm going to put a solar panel on my building next year and want to know how much sun it receives. Do you have a sensor that measures that?
+ Do these sensors need to be recalibrated?
+ How do I wire these sensors to my data logger?
+ Which wire is which on my three-wire sensor or millivolt adapter?
+ What if I wire my sensors incorrectly?
+ I entered the wrong multiplier into my datalogger. Can I fix it so I don't lose all my data?
+ My datalogger says I can only do 4-20 mA or 0-5 V inputs. Can I still use your sensors?
