Introduction

This product is the waterproof version of the DS18B20 temperature sensor, specifically designed for temperature measurements in distant or humid environments. This temperature & humidity sensor has a wide temperature range of -55°C to 125°C, but we recommend keeping the included PVC jacketed cable below 100°C to ensure optimal performance and durability.

The DS18B20 waterproof temperature sensor is a digital sensor that maintains signal integrity even over long distances. It utilizes a 1-Wire interface, connecting to a central microprocessor through a single wire (along with a ground wire). This design simplifies installation and connection, making it particularly suitable for systems operating within the 3V~5.5V range.

Each DS18B20 temperature sensor has a unique silicon serial number, useful for verifying its authenticity and enabling the connection of multiple sensors on a single 1-Wire bus. This feature facilitates the installation of temperature sensors in various locations for applications like indoor temperature monitoring, smart home integration, object temperature detection, greenhouse farming, and more.

With our plugable terminal, there is no soldering required to connect to our IO Expansion Shield. This allows you to conveniently integrate the DS18B20 temperature sensor into your project, saving you time and effort.
