DS18B20 PROBE WATER TEMPERATURE SENSOR

The DS18B20 Waterproof Temperature Probe features a stainless steel enclosure and 1m cable, making it ideal for liquid and wet environment temperature sensing. Uses the 1-Wire protocol — only one digital pin needed, and multiple probes can share the same pin. Each sensor has a unique 64-bit factory-burned ID. Compatible with 3.0–5.5V systems.

Note: Use a 4.7kΩ pull-up resistor from DATA to VCC. Probe wire length may vary ±3%.

Wire Connections:

• Red — VCC (3V–5.5V)
• Yellow/White — DATA (1-Wire)
