Temperature sensors are a specific type of sensor that measures the temperature or temperature gradient. They typically consist of a measurement element that detects the change in temperature. Temperature sensors work based on different principles and react to temperature changes differently. A few common temperature sensors include RTDs(Resistance Temperature Detector), thermistors, thermocouples, infrared measurements, and thermostats - each of these has a range of temperature that is more accurate, with advantages and disadvantages.
