2022-10-09 07:15:11
| DS18B20 Temperature Sensor | PT100 Temperature Sensor | |
| 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. |
