1PCS DS18B20 Stainless steel package Waterproof DS18b20 temperature probe temperature sensor 18B20 For Arduino(100CM)

This waterproof DS18B20 temperature probe features a sealed stainless steel housing and a 100cm lead, making it perfect for wet or harsh environments. It is ideal for Arduino hobbyists, makers, and educators building environmental monitoring systems, liquid temperature monitors, or smart agriculture projects.

Original DS18B20 sensing chip

At the heart of this probe is an original DS18B20 temperature sensor chip, ensuring reliable and accurate thermal measurements. It operates on a flexible 3.0V to 5.5V power supply, making it highly compatible with a wide range of microcontrollers.

Waterproof stainless steel housing

The sensor is enclosed in a high-quality, anti-rust stainless steel pipe measuring 6mm by 50mm. This robust waterproof packaging protects the internal electronics, allowing for safe submersion and outdoor deployment.

Single-bus interface design

Minimise your wiring complexity with the unique single-bus interface that requires no external components to operate. This protocol allows multiple sensors to share a single data line, saving valuable GPIO pins on your development board.

Adjustable resolution and wide range

This probe supports a wide temperature measurement range of -55 to +125 degrees Celsius. It features an adjustable resolution from 9 to 12 bits, giving you precise control over your data accuracy and conversion speed.

Individually tested and wrapped

Every probe undergoes rigorous testing to guarantee performance before being individually wrapped. The generous 100cm lead length provides ample reach for remote sensing applications.
