DS18B20 Temperature Sensor offers high accuracy, reliability, and anti-interference. Suitable for electronics projects, it supports temperature from -55°C to +125°C.
Supply lead. DFRobot wiki Pinout lists Red wire - VCC for the DS18B20 waterproof temperature sensor.
Ground lead. DFRobot wiki Pinout lists Black wire - GND.
1-Wire digital data lead. DFRobot wiki lists Yellow wire - DATA and says the interface requires one digital pin for communication.
| Pin | Position | Type | Function | Voltage |
