DS18B20
Brand: Analog Devices
The DS18B20 is a 1-Wire digital temperature sensor that reports -55°C to +125°C readings over a single DQ data pin, with each device carrying a unique 64-bit ROM code so many sensors can share one bus. Programmable 9- to 12-bit resolution and an optional parasite-power mode — running entirely off the data line — make it a common choice for wiring-constrained embedded temperature monitoring.

Sensor Features & Applications
- Single-wire 1-Wire bus reads temperature with only one DQ pin, cutting wiring versus analog sensors
- Programmable 9- to 12-bit resolution trades conversion time for finer temperature steps
- ±0.5°C accuracy from -10°C to +85°C fits general industrial and consumer thermal monitoring
- Parasite-power mode runs the sensor entirely from the DQ data line, eliminating a separate VDD wire
- Each device carries a unique 64-bit ROM code, letting many sensors share one 1-Wire bus
- -55°C to +125°C operating range and a 3-pin TO-92 package suit rugged embedded designs
