 Temperature Sensor :  A temperature sensor is a device that is designed to measures temperature changes in an environment or object. It  detects coldness or heat of an object and then convert it into an electrical signal. The most common unit of temperature is  Celsius, Fahrenheit, Kelvin. The S.I unit is kelvin. It has the symbol K. The principle of a temperature sensor is based on the relationship between temperature and a measurable physical property. Different types of temperature sensors operate on various principles. Four types of temperature scales are Celsius, Fahrenheit, Kelvin scales.   Temperature sensors fall into two main categories, depending on the type of application used or the industry you work in. TYPES : 1. Contact temperature sensors     It  measure the hot or cold level of an object or substance by direct contact. They are used to detect various temperatures in different solids, liquids or gases. 2. Non-contact temperature s...

SENSORS:      A sensor is a device that detects and measures physical properties  such as temperature, light, motion, pressure, or humidity. Then it converts these measurements into signals that can be read by other devices, like computers and allowing them to respond or record the data.      It monitor and measures the changes in the environment and triggers the action to be complete a task. This could include controlling the temperature of a room, switching on or off motors, or even running an entire manufacturing line. USES:      Sensors are used in a wide range of applications.      It is used in every fields and day to day applications like smart phones, automobiles ,wearable devices, etc..      It is also used in central to industrial applications being used for process control, monitoring, and safety. Sensors are also central to medicine being used for diagnostics, monitoring, critical care, and publi...
