Temperature Sensor Comparison

Temperature Sensor (UB-DT-P1) PT100 Temperature Sensor (UB-PT-N1)
Measurement Principle Commonly used digital temperature sensors, with digital output signals. It has small size, low hardware overhead, high interference immunity and high accuracy. A platinum RTD whose resistance varies with temperature. At 0°C the resistance is 100 ohms and increases approximately uniformly as the temperature rises.
