Description
These 1-Wire digital temperature sensors offer good accuracy (±0.5°C over a wide range) and provide up to 12 bits of resolution from the onboard digital-to-analog converter.
They work well with any microcontroller using a single digital pin, and you can connect multiple sensors to the same pin, as each one has a unique 64-bit ID programmed at the factory for easy identification. Compatible with 3.0-5.0V systems, the sensor requires a 4.7k resistor as a pull-up from the DATA pin to the VCC line when used with a microcontroller.
