Sunshine duration is typically measured using a device called a sunshine recorder, which consists of a glass sphere that focuses sunlight onto a piece of paper. The recorder marks the duration of sunshine each day by burning a trace onto the paper. The length and intensity of the burn mark correspond to the amount of sunshine received.
A sunshine recorder, also known as a Campbell-Stokes recorder, is a common instrument used to measure sunshine duration. It consists of a glass sphere that focuses sunlight onto a card, which leaves a burn mark when the sun is shining. The length of the mark indicates the duration of sunshine.
The black box flight recorder was invented in Australia by Dr. David Warren in the 1950s. The device was initially called the Flight Data Recorder (FDR).
The black box flight recorder was invented by Australian scientist Dr. David Warren in the 1950s. It was created to help investigate and prevent air accidents by recording flight data and cockpit conversations.
The number of hours of sunshine in a day is recorded in an instrument called a Parheliometer. A solid glass ball focuses the Sun's rays on to a strip of card, moving along the as the Sun moves through the sky. The longer the marks, the longer the period of sunshine.

The Campbell recorder measures sunshine duration by recording when sunlight falls on its photocell. The photocell's electrical resistance changes when exposed to light, allowing the recorder to track periods of sunshine. This information is used to calculate the number of hours of sunshine during a specific time period.
The Campbell-Stokes recorder (sometimes called a Stokes sphere) is a kind of sunshine recorder. It was invented by John Francis Campbell in 1853 and modified in 1879 by Sir George Gabriel Stokes. The original design by Campbell consisted of a glass sphere set into a wooden bowl with the sun burning a trace on the bowl. Stokes's refinement was to make the housing out of metal and to have a card holder set behind the sphere. The unit is designed to record the hours of bright sunshine which will burn a hole through the card. sunshine recorder

Campbell Stokes Recorder: measures sunshine. This type of recorder is made up of a glass ball which concentrates sunshine on to a thick piece of card. The sunshine then burns a mark on the card which shows the number of hours of sunshine in the day.A Campbell Stokes Sunshine Recorder.Campbell Stokes RecorderCampbell Stokes Recordersciolagisye
