DS18B20 Water Proof Temperature Probe – Black (1m) Original Chip

Description

Product Short Description: Capture highly accurate, digital temperature readings in harsh or wet environments with the DS18B20 Waterproof Temperature Probe. Featuring a sealed stainless steel tip, a 1-meter black PVC cable, and an original Dallas/Maxim sensor chip, this probe utilizes a 1-Wire interface. It is the perfect reliable sensor for soil, water, or general IoT temperature monitoring.

Detailed Description: The DS18B20 is an industry-standard digital temperature sensor known for its precision and ease of use. Because this version features the original sensor chip, it guarantees stable, highly accurate readings and prevents the communication glitches often found in cheaper clone chips.

The sensor is encased in a waterproof, rust-resistant stainless steel cap and sealed with potting compound, allowing you to completely submerge the probe tip in liquids or bury it in soil without damaging the electronics.

Because it uses the 1-Wire digital protocol, you can connect multiple DS18B20 sensors to the exact same digital pin on your microcontroller. This makes it an exceptionally powerful addition to digital design and IoT hardware kits where pin availability is limited. It integrates seamlessly with development boards like the Arduino Uno, ESP32, and STM32 (both Blue Pill and Black Pill) using standard libraries.

Key Features:

• Original Chipset: Ensures high precision, long-term stability, and true 1-Wire compatibility.

• 1-Wire Interface: Requires only a single data pin (plus power and ground) for communication. Multiple sensors can share the same bus.

• Waterproof & Rugged: Sealed in a 6mm x 30mm stainless steel tube with a 1-meter thick black PVC cable.

• No Analog Drift: Sends a purely digital signal, meaning cable length does not degrade the accuracy of the reading.
