Take your sensing projects anywhere—wet or dry—with the DS18B20 Digital Temperature Probe. Housed in a rust-resistant stainless steel tube, this sensor utilizes the efficient 1-Wire protocol, allowing you to capture precise thermal data from liquids, soil, or freezers using just one digital pin on your microcontroller.
- IP67 Submersible Design: Encapsulated in a high-quality stainless steel casing that is completely sealed against moisture, making it the ultimate solution for aquarium monitoring, hydroponics, and soil temperature sensing.
- 1-Wire Bus Communication: Uses a specialized digital interface that requires only a single data line to transmit info, enabling you to daisy-chain multiple sensors to one microcontroller GPIO without occupying extra ports.
- Extreme Climate Range: Engineered to function reliably in harsh conditions from -55°C to +125°C (-67°F to +257°F), ideal for IoT weather stations and industrial process control.
- Parasite Power Mode: Capable of deriving power directly from the data line, which simplifies wiring for remote setups where running a separate power cable is difficult.
- Programmable Resolution: Features user-adjustable sensitivity settings (9 to 12 bits), allowing you to customize the balance between data conversion speed and readout precision for your data logger.
- Authentic Sensor Chip: Built with a genuine sensing element to ensure stable calibration and minimal drift, providing far superior accuracy compared to standard analog thermistors.
