measure the useful light that is illuminating the roadway and being seen by people. Silicon sensors, on the other hand, have peak sensitivity to infrared and red light; they are almost insensitive to blue and green. Thus silicon sensor controls have their turn ON and OFF radically affected by a cloud cover and atmospheric pollution.

6 FAQs about [Silicon Photocell as Light Meter]
How do you use a photocell meter?
Attach the red probe of your meter on one leg of your photocell while the black probe on the other leg. Its direction doesn’t matter, but you might need to utilize alligator clips to ensure the probes don’t slip from the leads of the photocell. Protect the photocell, so no light falls on it.
Can electric light meters use solar cells?
In theory, electric light meters COULD also have employed gallium arsenide cells, silicon or other non-selenium solar cells in special cases. EDIT: Or germanium photodiodes/phototransistors. That's it, as far as I know.
What is the optical part of a photo meter?
The optical part of such a meter is a window in front of the photo cell's light-sensitive side. The window's surface is usually structured like a honeycomb made of convex lenses. This type of window helps to bundle the light coming from the direction in which the photo cell is pointed.
Does a digital camera use a light meter?
Some modern digital camera designs however will use the (CMOS or CCD) imaging sensor itself as a light meter (which is technically speaking a silicon photodiode based meter). Also, mind that there were multi-segment CDS designs, some of which were also TTL (both to be found in the Minolta SR-T series).
Do film cameras have a light meter?
There are a number of light meters built into film cameras I am aware of. First there's selenium cell light meters, like on the below old Canonet. Later cadmium sulphide (CdS) photocells became more common. This later Canonet model used one. It's right above the lens' front element.
What is a light meter used for?
The most common use of such light meters is measuring the exposure value for photography. The electric part of such a meter is an electromagnetic measuring instrument which is connected to the anode and cathode of a selenium photo cell that produces more or less electric power when exposed to more or less light.
