The DS18B20 is a high-precision, waterproof digital temperature sensor probe designed for harsh environments. Encapsulated in a high-quality stainless steel tube, this sensor is moisture-proof and rust-resistant, making it ideal for measuring liquid temperature, soil temperature, or outdoor monitoring.

Unlike analog sensors, the DS18B20 sends data via a 1-Wire digital serial bus, ensuring that the temperature reading remains accurate even over long distances without signal degradation. It is fully compatible with popular microcontrollers like Arduino, Raspberry Pi, and ESP8266.

Key Features:

• Waterproof Design: Stainless steel probe (6x50mm) prevents rust and short circuits in wet conditions.
• Digital Accuracy: 9 to 12-bit adjustable resolution with direct digital signal output.
• Wide Range: Measures temperatures from -55°C to +125°C (-67°F to +257°F).
• 1-Wire Interface: Requires only one digital pin for communication.
