DS1820 Frequently Asked Questions (FAQ)
-
The DS1820 has an accuracy of ±0.5°C from -10°C to +85°C, and ±1°C from -40°C to +125°C.
-
You can connect multiple DS1820 sensors to a single bus by assigning a unique 64-bit ROM code to each sensor. The master device can then address each sensor individually using its unique ROM code.
-
The maximum cable length for the DS1820 is 100 meters (330 feet) for a single sensor, and 20 meters (66 feet) for multiple sensors on a bus.
-
To minimize power supply noise and EMI, use a decoupling capacitor (e.g., 0.1 μF) between VCC and GND, and consider using a shielded cable or twisted pair wiring for the 1-Wire bus.
-
Yes, the DS1820 can operate in high-temperature environments up to 125°C, but the accuracy may degrade above 100°C. Consult the datasheet for temperature coefficient data.
