Digital thermometer flexible tip
There are many different types of digital thermometers, depending on the use and the situation. The most common type include those used for checking body temperature, air temperature and food temperature. These thermometers, while relatively recent inventions, are still very affordable.
Digital thermometers work by making use of a temperature sensor called a thermoresister. This device changes it resistance based on what the temperature is. Sensors, usually some type of circuit board or very low-powered computer, then take that information and interpret it into a temperature. Digital thermometers then display that on an easy-to-read layout.
The most common type of digital thermometer in the home is likely that associated with the thermostat. Though a thermostat can be the traditional dial thermometer, many are choosing to use digital thermometers not only for the easy reading layout but also the fact they are programmable. However, in many cases, the temperature sending properties work the same.
This is also true for an outside thermometer that transmits temperatures to a digital readout. Wireless digital thermometers have more technology, simply because they transmit data from one location to another, usually over a relatively short distance of 100 feet (35 meters) or less. In some cases, these may have two readouts, one at the sensor and one on a receiver inside the home. This makes it convenient for those to see the temperature wherever they are.
