Detect Total Light
Detect Total Light
(OP)
Hello there,
This is a real novice question as my field is software.
What electronic component(s) can be used to measure the
total visible/infra-red light shining?
Perhaps something that makes a current or the current
changes. Or is there some other way of doing this?
Sorry for my simple explanation.

How much energy, from what kind of source, to what accuracy, etc.

In general, you need a photometer or radiometer to measure "light" that comes in the form of photons.
The actual detectors generally sense photons, so they're typically photodiode-like devices.
There are other detectors that change their outputs as a function of temperature, like pyroelectric detectors.

they are also call photovoltaic cells, have peak sensitivity is in the very near infrared (about 800 to 900 nM
use an amplifier configuration "transimpedance amplifier" which will convert the photogenerated current to a voltage and the current will be proportional to the light intensity over at least 6 orders of magnitude.
saturation can occur at somewhat over 4X the illumination from the sun on a clear day.
