2. List of weather instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_weather_instruments

   Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction; Present Weather/Precipitation Identification Sensor for identifying falling precipitation; Disdrometer for measuring drop ...

3. Hygrometer - Wikipedia

   en.wikipedia.org/wiki/Hygrometer

   A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.

4. Thermo-hygrograph - Wikipedia

   en.wikipedia.org/wiki/Thermo-hygrograph

   A thermo-hygrograph. A thermo-hygrograph or hygrothermograph is a chart recorder that measures and records both temperature and humidity (or dew point).Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity.

5. Indoor–outdoor thermometer - Wikipedia

   en.wikipedia.org/wiki/Indoor–outdoor_thermometer

   In an indoor–outdoor thermometer based on a conventional liquid-in-glass thermometer, the stem of the outdoor thermometer is connected to the bulb by a long, flexible or semi-rigid capillary. The temperature scale is marked on the stem as usual. However, the temperature that is actually measured is the temperature at the bulb. [1]

6. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...

7. Wet-bulb globe temperature - Wikipedia

   en.wikipedia.org/wiki/Wet-bulb_globe_temperature

   T w = Natural wet-bulb temperature (combined with dry-bulb temperature indicates humidity) T g = Globe thermometer temperature (measured with a globe thermometer, also known as a black globe thermometer) T d = Dry-bulb temperature (actual air temperature) Temperatures may be in either Celsius or Fahrenheit; Indoors the following formula is used:

8. Temperature data logger - Wikipedia

   en.wikipedia.org/wiki/Temperature_data_logger

   They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with personal computers or smart phones for set-up, control, and analysis. Some include other sensors such as relative humidity, wind, light, etc. Others may record input from GPS ...

9. Infrared thermometer - Wikipedia

   en.wikipedia.org/wiki/Infrared_thermometer

   An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called black-body radiation emitted by the object being measured. They are sometimes called laser thermometers as a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns , to describe the ...
