In scientific language a thermometer is used for measuring the temperature of various components of which the main component is human body in which the body temperature is measure with the help of temperature. Liquid crystal display thermometer is a type of thermometer which contains heat sensitive liquid crystals which are in a plastic strip which changes color to indicate different temperatures. This liquid crystal possesses the mechanical properties of a liquid which also have optical properties of a single crystal. Temperature changes could affect the color of a liquid crystal as it has optical properties of single crystal which is unique and very much innovative. Liquid crystal display thermometers portray temperatures as color which can be used for reading body temperature by placing against forehead.These liquid crystal display thermometers are very commonly used in aquariums, in home brewing and also in mood rings. This thermometer is used in medical devices which make use of the known heat sensitive color which changes the chemical embedded in the device for measuring the temperature of the skin. The main features of the normal thermometer are that these are very durable and reliable and have that flexibility, comfort and ease to read the figures or scales. These thermometers should be weather resistant, water resistant and should last for long. Manual thermometers are very much reliable in comparison with that of the other thermometers.
The main parts of these liquid crystal display thermometers are very much used for measuring voltage, the other part which is included in this thermometer is known as ic socket, and then the other one includes diode for temperature sensor, resistors, film capacitor, printed board, shielded wiring thermal and stud. The specifications of these parts include the ic displays the analog voltage in the digital and the ic socket is used for installing. The diode is used as the temperature sensor as the original use of this diode is for switching purpose. Film capacitors are used for measuring the input voltage as it influences the precision of the measurement.
