What is a temperature sensor?

A temperature sensor is a device that detects and measures temperature, usually in degrees Celsius (°C) or Fahrenheit (°F), and converts it into a readable output.

How do temperature sensors work?

Temperature sensors work based on the principle of detecting changes in physical properties as temperature varies. Common types include thermocouples, resistance temperature detectors (RTDs), and thermistors, each utilizing different mechanisms to measure temperature.

What is the accuracy of temperature sensors?

Accuracy varies depending on the type and quality of the sensor. High-precision sensors can have accuracies within fractions of a degree, while cheaper or less precise sensors may have larger tolerances.
