Arduino Interfacing Multiple DS18B20 Digital Temperature Sensors with Arduino One of the DS18B20's features is that multiple DS18B20s can coexist on the same 1-Wire bus. Because each DS18B20 is pre-programmed with a unique 64-bit serial code, they can be distinguished from one another. The DS18B20 temperature sensor is a 1-wire digital temperature sensor. Each sensor has a unique 64-bit serial number, which means you can use many sensors on the same data bus (this means many sensors connected to the same GPIO). This is specially useful for data logging and temperature control projects.
Interfacing Multiple DS18B20 Temperature Sensors to Arduino
Step 1: Connect the DS18B20 sensors to the Raspberry Pi In the connection diagram below you see a circuit to connect three DS18B20 temperature sensors to a raspberry Pi, with the help of a breadboard. If you want to connect a single DS18B20 temperature sensor, just remove 2 sensors from this circuit. Step 2: Active a One Wire GPIO One of the advantages of the DS18B20 temperature sensor is its ability to support multiple sensors on the same 1-Wire bus. Each DS18B20 has a unique 64-bit serial code, allowing for easy differentiation between sensors. In this tutorial, we will demonstrate how to read the temperature from multiple DS18B20 sensors connected to the same bus. The DS18B20 temperature sensor is a one-wire digital temperature sensor. This means that it just requires one data line (and GND) to communicate with your ESP32. It can be powered by an external power supply or it can derive power from the data line (called "parasite mode"), which eliminates the need for an external power supply. The DS18B20 temperature sensor is a 1-wire digital temperature sensor. This comes with sealed package lets precisely measure temperatures in wet environments with a simple 1-Wire interface. It communicates on common bus. It means it can connect several devices and read their values using just one digital pin of the Arduino.

I have included wiring diagrams and several example codes to get you started. For this tutorial, we will be using the DallasTemperature in combination with the OneWire Arduino library. DS18B20 Sensor Specifications. Programmable Digital Temperature Sensor. Communicates using the 1-Wire method. Operating voltage: 3V to 5V. Temperature Range: -55°C to +125°C. Accuracy: ±0.5°C. Output Resolution: 9-bit to 12-bit (programmable) A unique 64-bit address enables multiplexing. As you know this temperature sensor uses one wire protocol for communication purposes. Each sensor comes with a unique 64-bit serial code which makes it easy to connect several DS18B20 sensors on the same one-wire bus. Thus, we will read the temperature readings from multiple DS18B20 sensors by connecting them through a single GPIO.
