Digital Wired Thermometer is easy to use and read, just put the probe cable out to get indoor and outdoor temperature information. No programming is required.
The digital wired thermometer is a device that measures the temperature of the indoor or outdoor atmosphere. The most common type consists of a long tube that contains mercury or colored alcohol at the base, although there are also other kinds, such as spring and digital thermometers. When the atmospheric temperature rises, it causes the material inside the air thermometer to expand. Conversely, when the air gets colder, the material contracts and travels back down. Thermometers use temperature scales, either Fahrenheit, Celsius, or Kelvin, to provide a measurement of heat in degrees.
In general, the idea of an air thermometer is based on the fact that liquids and gases expand when they are heated and contract when they are cooled. The first air thermometers used the same basic mechanics as many of the instruments used today: a glass tube filled at the end with mercury or colored alcohol that rises through the tube as it is heated. The first thermometers contained water, but later versions switched to alcohol or mercury because their freezing points are lower.
A digital thermometer contains heat-sensitive material and displays the temperature measurement on an electronic screen rather than on a printed scale. Digital thermometers can often work more quickly than other types.
