The Invisible Pulse: A Guide to Temperature Sensors
Temperature is one of the most frequently measured physical quantities in the world. From the thermostat in your living room to the complex cooling systems in a spacecraft, temperature sensors act as the "nervous system" for modern technology, converting thermal data into signals we can monitor and control.
What is a Temperature Sensor?
At its core, a temperature sensor is a device designed to measure the hotness or coldness of an object or environment and convert that data into a readable format. This is usually achieved through a change in a physical characteristic—such as electrical resistance or voltage—that corresponds to a change in temperature.
