The maximum cable length for the DS18B20-PAR is 100 meters, but it's recommended to keep it as short as possible to minimize signal degradation and noise.
Yes, you can use multiple DS18B20-PAR sensors on the same bus, but each sensor must have a unique address. The DS18B20-PAR has a unique 64-bit serial code that allows multiple sensors to be connected to the same bus.
In parasite power mode, the DS18B20-PAR derives its power from the data line. To handle parasite power mode, ensure that the data line is pulled high to VCC through a resistor (typically 4.7kΩ) and that the VCC pin is left unconnected.
The DS18B20-PAR has an accuracy of ±0.5°C from -10°C to +85°C, and ±1°C from -40°C to +125°C.
Yes, the DS18B20-PAR has built-in noise filtering and can operate in noisy environments. However, it's still recommended to use proper noise reduction techniques, such as shielding and grounding, to ensure reliable operation.
