Hi all,
I have an Apogee SQ-500 quantum sensor that I hook up to my multimeter in order to get a reading from (it measures photosynthetically active light in units of micromoles per meter squared per second).
My problem is that my multimeter only reads down to a millivolt and one millivolt is equal to 100 micromoles per meter squared per second with this sensor. As a result, I can only get a reading of 100 (1mV) 200 (2mV), 300 (3mV) etc., but I would like to get more detailed readings (e.g - 100, 110, 120). To do this, I'll need to amplify a 10 microvolt signal up to a 1 milivolt signal, so each millivolt is equivalent to 1 micromole per meter squared per second.
From what I understand, I'll need an amp that can do 100x gain, but I don't know enough about this to find the right component. Can you please help a noob out?
