No. The sun dial was an early device to help tell time.
A thermometer placed in sunlight will measure the temperature of the air surrounding it, not the temperature of the sun itself. The sun's rays can heat up the air, which in turn affects the temperature measured by the thermometer.
No. The thermometer measures the temperature of mass or material. Concerning the moon, a thermometer could measure the temperature of dust or rock on the surface. If it were not in contact with the surface, and the sun shone on it, the thermometer would read the temperature to which the sun heated it. If it were shielded from the sun, then the thermometer would read the temperature of space ... about 3 K, or darn near absolute zero.
When a thermometer is placed in direct sunlight, it will not accurately read the air temperature. Instead, it will measure the temperature of the thermometer itself, which can be influenced by the direct heat from the sun. This can cause the thermometer to show a higher reading than the actual air temperature. Ideally, thermometers should be shielded from direct sunlight to provide an accurate measure of air temperature.
When a thermometer is left in sunlight, it can absorb heat and give a falsely high temperature reading due to radiant energy from the sun. It's important to shield the thermometer from direct sunlight to get an accurate temperature measurement.
If a thermometer is placed in direct sunlight, it will likely read a temperature that is higher than the actual air temperature. This is because the thermometer will absorb heat from the sunlight, which can cause it to register the temperature of the sun's rays rather than the surrounding air. The material and design of the thermometer can also affect its reading, as some types may respond more to radiant heat than others.
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.

It is best to place your thermometer in the shade to get an accurate reading of the air temperature. Direct sunlight can affect the reading by warming up the thermometer and giving a higher temperature measurement.
One method that was used by the early Greeks was the Sun Dial.
Sun Dial was created in 1990.
The plural is sun dials.
The thermometer readings in the drawer were typically lower than in direct sunlight. This is because objects in the drawer are shielded from direct heat and radiation from the sun, resulting in a cooler temperature reading.
