Waterproof DS18B20 Temperature Sensor (1m)

Reliable Digital Temperature Monitoring in Harsh Environments

The DS18B20 Waterproof Temperature Sensor is the industry-standard choice for precise, long-range digital temperature acquisition. Unlike analog thermistors, this sensor communicates via a digital 1-Wire interface, which means you only need one single data pin from your Arduino, ESP32, or Raspberry Pi to read the temperature data.

The sensor is housed in a stainless steel tube, ensuring excellent thermal conductivity and protection against rust or chemical damage. Because each sensor has a unique 64-bit serial code, you can easily daisy-chain dozens of these probes on the same wire, making it possible to create highly granular multi-point thermal monitoring systems for smart farms, industrial vats, or home automation.

Key Features:

• Submersible Design: The stainless steel probe is fully sealed, making it safe for long-term immersion in liquids and wet environments.
• 1-Wire Digital Interface: Requires only one digital I/O pin and a 4.7kΩ pull-up resistor (common in Arduino examples) for data transmission.
• High Precision: Provides ±0.5°C accuracy over a wide range (-10°C to +85°C).
• Expandable Architecture: Connect multiple sensors to a single bus, ideal for complex environmental logging projects.
