DFRobot Gravity Waterproof DS18B20 Temperature Sensor Kit

The DFRobot Gravity Waterproof DS18B20 Temperature Sensor Kit is a waterproof digital temperature sensor kit that operates from 3.0 V to 5.5 V. It is designed for simple, direct connection to Arduino and other microcontroller boards without complex external circuitry.

The kit uses the DS18B20 digital temperature sensor, which communicates over a 1-Wire interface. Only a single data wire plus ground is required to connect multiple sensors to a central microprocessor, which simplifies wiring in multipoint measurement projects.

Overview

The probe is pre-wired with a built-in resistor module, allowing straightforward connection to compatible boards. The probe is encased in a waterproof housing, making it suitable for applications where exposure to moisture is a concern. The digital output supports stable and interference-resistant readings for both hobbyist projects and more demanding industrial scenarios.

Applications

The sensor kit is used across a range of fields where durability and precision are required. Typical applications include:

• Monitoring soil temperature for agriculture and gardening
• Controlling temperatures in hot water tanks and environmental chambers
• Ensuring stable conditions in systems such as refrigerators and barns
• Temperature monitoring in telecommunication rooms and power communication rooms
• Cable temperature monitoring where reliable data is critical
