Digital Temperature Sensor

Digital temperature sensors have an Internal Integrated circuit that will handle the temperature conversion.

The temperature value is placed in a digital register location. This temperature reading is available and transmitted when the correct command protocol has been used with the relevant addresses and instructions.

protocols include I2C , SPI and OneWire.

Digital temperature sensors can simplify electronic design and sometimes reduce amount of code needed to successfully read the temperature , however they are normally more expensive than passive temperature sensors.
