1-Wire Protocol Sensors
Compatible with ESP32

The list of sensors using 1-Wire protocol for your ESP32 projects, complete with wiring guides and code examples.

The 1-Wire protocol allows digital data communication over a single data line, making it highly efficient for minimal wiring applications. It’s most commonly used with sensors like the DS18B20 digital temperature sensor.

With only one data pin and a ground connection, this protocol is ideal for low-cost temperature sensing with ESP32 or Arduino. Libraries like OneWire and DallasTemperature simplify integration into the Arduino IDE.

1-Wire also supports multiple devices on a single bus, thanks to unique addresses assigned to each sensor.
