  Temperature Sensors: A temperature sensor is an electronic device that measures the temperature of its environment and converts the input data into electronic data to record, monitor, or signal temperature changes. There are many different types of temperature sensors. Some temperature sensors require   direct contact   with the physical object that is being monitored (contact temperature sensors), while others indirectly measure the temperature of an object (non-contact temperature sensors).   Non-contact temperature sensors are usually infrared (IR) sensors. They remotely detect the IR energy emitted by an object and send a signal to a calibrated electronic circuit that determines the object's temperature. Among the contact temperature sensors are  thermocouples and thermistors . A thermocouple is comprised of two conductors, each made of a different type of metal, that  are joined at an end  to ...

  What are Sensors, Detectors, and Transducers? Sensor /Detectors/Transducers are electrical , opto-electrical, or electronic devices composed of specialty electronics or otherwise sensitive materials, for determining if there is a presence of a particular entity or function. Many types of sensors, detectors , and transducers are available including those for detecting a physical presence such as flame, metals, leaks, levels, or gas and chemicals , among others. Some are designed to sense physical properties such as temperature , pressure , or radiation, while others can detect motion or proximity . They operate in a variety of manners depending on the application and may include electromagnetic fields, or optics, among others. Many applications over a wide range of industries use sensors , detectors, and transducers of many kinds to test, measure, and control various processes and machine functions. With the advent of the  Internet of Things (IoT) , the need for sensors as a...
