There are instruments called Ceilometers which can measure cloud height and cover, but they're not especially accurate for cover (they are quite good for cloud height, especially at night) as a cloud can sit over the instrument and give a false reading. Also, unless cloud passes over them they give a false negative. The best instrument for measuring cloud cover is a trained Mark I eyeball (or two)

An Okta is a measurement unit used to describe cloud cover over a defined area. In aviation 10% cloud cover is considered one peg up from clear to a few clouds, mainly scattered.
Cloud cover is usually given as a percentage, there is no unit of measure.
There are several instruments used to predict the weather in most cases, but the ones that determine whether there will or will not be rain are:Barometer - measures air pressurePsychrometer - measures relative humidityAnemometer - measures wind speedWeather maps - used by meteorologists to collect dataWeather satellites - used to track large-scale air movements; the data these collect are analyzed by meteorologists and computers
The instrument used to measure humidity is called a hygrometer.
The instrument used to measure humidity is called a hygrometer.
Instrument which is used to measure canopy cover
A nephoscope is an instrument used to measure the height, direction, and velocity of clouds. It works by reflecting sunlight off the cloud and measuring the angles of reflection to determine cloud characteristics.

A nephoscope is an instrument used to measure the altitude and angle of clouds in the sky by visually tracking their movement relative to the instrument. By observing the movement of clouds against the gridded field of view of the nephoscope, the observer can estimate the cloud base height and direction.

No. The instrument used to measure wind speed is an anemometer.
The instrument which is used to measure snowfall is called a snow gauge.
A thermometer
Ty Beck, 1897, English man working outside and realized using light that you can measure the base of a cloud.
There is no single instrument for either of these things
