Discussion:
2.5.1 The Neulog light sensor (NUL-204)
The NUL-204 can be used for any science experiment where light intensity
measurements are required, such as Chemistry, Physics, Biology, Environmental
Science, etc.
This sensor can be used to take light measurements in low, medium and high light
intensity environments, such as in classrooms and in open sunlight. The sensor
can be used to measure both fast light changes like those produced by light bulbs
connected to an AC supply, as well as the light intensity of a bulb or near steady
levels outside on a sunny day.
The measurement unit for all three data collection ranges (low, medium, high) is
the lux.
Lux (lx, or lux): The SI unit of light intensity.
NUL-204 includes a photodiode, which reacts with photons to release free
electrons (photoelectrons). The amount of light striking the sensor is directly
proportional to the voltage generated by the photoelectrons released. The sensor
measures the general voltage released and thus calculates the light intensity.
