DS18B20/T&R Frequently Asked Questions (FAQ)
-
Theoretically, up to 255 devices can be connected to a single bus, but in practice, the maximum number is limited by the bus capacitance and the pull-up resistor value. A good rule of thumb is to limit the number of devices to 10-20 per bus.
-
In rare cases, multiple devices may have the same ROM code. To handle this, use the 'strong pull-up' method during the ROM search process, or use a more advanced search algorithm that takes into account the device's unique 64-bit ROM code.
-
The recommended operating voltage range for the DS18B20 is 3.0V to 5.5V. However, the device can operate down to 2.8V with reduced accuracy and up to 6.0V with proper bypassing and decoupling.
-
To ensure accurate temperature readings in high-noise environments, use a shielded cable, keep the sensor away from noise sources, and use a low-pass filter or averaging technique to reduce noise. Additionally, consider using a more advanced temperature sensor with built-in noise reduction features.
-
Yes, the DS18B20 can be used in a parasitic power mode, where the device is powered from the data line. However, this mode requires careful design and layout to ensure reliable operation, and is generally recommended for low-power, low-speed applications.
