Most of the sensor systems rely on light as the signal source. LEDs are often ideal as a light source due to their high efficiency.
The thermometer was developed over several years by a number of people - Cornelis Drebbel, Robert Fludd, Galileo Galilei and Santorio Santorio. The word thermometer was derived from two Greek word fragments – ‘thermo’ meaning ‘heat’ and ‘meter’ meaning ‘to measure’.

Broadly speaking, pyrometers belong to a class of thermometers that are used for measuring only high temperatures. However, today they have been modified to measure low temperatures as well.
A bolometer is a highly sensitive instrument used for detecting heat or electromagnetic radiation. It was invented by Samuel Pierpont Langley, an American astronomer, in 1878. This instrument was initially used in combination with a telescope to quantify infrared radiation.
Noncontact sensors using capacitive and eddy-current technologies each represent a unique blend of advantages and disadvantages for a variety of applications.
Eddy current and capacitive noncontact displacement sensors are becoming a standard technology for z-height measurement due to their compactness, flexibility, ease of use, high resolution, noncontact nature and robust design.
