A temperature sensor is a device which provides temperature measurement through an electrical signal. The most common types are Thermocouple, Resistance Temperature Detector (RTD) and Thermistor. These are some of the most commonly used in the internet of things.   Thermocouple A thermocouple (T/C) is made from two dissimilar metals that generate electrical voltage in direct proportion to changes in temperature. A T/C is made … Continue reading IoT Devices – Temperature Sensor »
