Keyestudio DS18B20 Temperature Sensor Module for Arduino - Digital Output

This module uses the digital 1-Wire communication protocol. It requires only a single data line (plus power and ground) to communicate with your microcontroller, simplifying wiring. Libraries like DallasTemperature for Arduino facilitate easy reading of temperature values.

Yes, the module is designed to operate across a supply voltage range of 3.3V to 5V DC. Ensure your microcontroller's logic level is compatible with the sensor's data line; most modern boards handle this communication correctly at either voltage.

Multiple DS18B20 sensors can be connected in parallel on the same 1-Wire bus. Each sensor has a unique 64-bit ROM address. You use the DallasTemperature library to address each sensor individually. A 4.7kΩ pull-up resistor on the data line is typically required, which is already included on this module.

The DS18B20 has a standard accuracy of ±0.5°C over much of its range. Its resolution is software-configurable from 9 to 12 bits, corresponding to increments of 0.5°C, 0.25°C, 0.125°C, and 0.0625°C, respectively. The default resolution is often 12-bit.
