DS18B20 Waterproof Digital Temperature Sensor Probe 100cm is a 1 Meter Long Waterproof, sealed and pre-wired digital temperature sensor probe based on DS18B20 sensor.
DS18B20 1-wire digital temperature sensors comes with ±0.5°C with up to 12 bits of precision.
1-Wire DS18B20 can with range microcontrollers using a single digital pin, You can connect multiple ones to the same pin, as each sensors one comes with a unique 64-bit address.
DS18B20 Sensor Specifications
- 9 to 12 bit selectable resolution
- Uses 1-Wire interface- requires only one digital pin for communication
- Unique 64 bit ID burned into chip
- Multiple sensors can share one pin
- ±0.5°C Accuracy from -10°C to +85°C
- Temperature-limit alarm system
- Query time is less than 750ms
- Usable with 3.0V to 5.5V power/data
Note: You need to connect a 4.7k resistor to sensing pin, which is required as a pull-up from the DATA to VCC line.
