DS18B20 Digital Temperature Sensor
DS18B20 Digital Thermometer
The DS18B20 is a digital thermometer that provides precise Celsius temperature measurements with user-selectable resolution from 9 to 12 bits. It communicates via a 1-Wire interface, requiring only one data line and ground for communication with a microcontroller.
It’s ideal for:
- Thermostatic controls and industrial systems
- Consumer electronics and thermally sensitive applications
- Distributed temperature sensing with multiple sensors on a single bus
This sensor can operate in parasite power mode, drawing power directly from the data line, eliminating the need for an external power supply.
