Frequently Asked Questions

What is the operating voltage range for the DS18B20T sensor?

The DS18B20T operates from a 3.0V to 5.5V DC supply. It can also be powered in parasitic mode directly from the 1-Wire data line when the bus is held high, eliminating the need for a local VCC connection.

How do I connect multiple DS18B20T sensors to a single microcontroller pin?

Multiple DS18B20T sensors can be connected in parallel to a single microcontroller GPIO pin using the 1-Wire bus protocol. Each sensor has a unique 64-bit ROM address, allowing the master device to query them individually. Ensure you use a 4.7kΩ pull-up resistor on the data line.

What is the typical accuracy and temperature resolution of this sensor?

The DS18B20T offers a typical accuracy of ±0.5°C within the -10°C to +85°C range. Its resolution is programmable from 9 to 12 bits, corresponding to temperature increments of 0.5°C, 0.25°C, 0.125°C, or 0.0625°C, allowing a balance between conversion speed and precision.

Can I use this sensor with 5V microcontrollers like Arduino Uno?

Yes, the DS18B20T is fully compatible with 5V systems like the Arduino Uno. Connect VDD to 5V, GND to ground, and the data line to a digital pin with a 4.7kΩ pull-up resistor to 5V. Many Arduino libraries, such as DallasTemperature, are available to simplify communication.
