Frequently Asked Questions

What is the operating voltage range for the DS18B20Z sensor?

The DS18B20Z operates from a wide voltage range of 2.5V to 5.5V DC. This makes it directly compatible with both 3.3V and 5V microcontroller systems like Arduino, ESP32, and Raspberry Pi without requiring a level shifter.

How do I communicate with the DS18B20Z using a microcontroller?

Communication is via the 1-Wire digital protocol. You only need a single microcontroller GPIO pin connected to the sensor's data line, with a pull-up resistor (typically 4.7kΩ) to VCC. Libraries like OneWire and DallasTemperature are available for Arduino to simplify reading temperature values.

What is the accuracy and temperature range of this sensor?

The sensor offers ±0.4°C accuracy within the -10°C to +85°C range. Its full specified operating range is from -55°C to +125°C, though accuracy may vary at the extremes. The programmable 9 to 12-bit resolution allows you to balance conversion speed and precision.

Can I connect multiple DS18B20Z sensors to one microcontroller pin?

Yes, the 1-Wire protocol supports multi-drop mode. Each DS18B20Z has a unique 64-bit serial code, allowing many sensors to share the same data bus. You must use the appropriate library commands to address each sensor individually for reading temperatures.
