Waterproof DS18B20 Digital Temperature Sensor Kit With 1 Wire Interface For Arduino And IoT Projects
The Gravity DS18B20 Waterproof Temperature Sensor Kit is a reliable and easy-to-use temperature measurement solution designed for Arduino, ESP32, Raspberry Pi, and other microcontroller platforms. The kit includes a waterproof DS18B20 digital temperature probe and a dedicated resistor module with a pluggable terminal adapter, enabling quick installation without soldering. Its waterproof construction makes it suitable for liquid temperature monitoring, environmental sensing, and outdoor applications where conventional sensors may not perform reliably.
Based on the DS18B20 digital temperature sensor, the module provides configurable 9-bit to 12-bit temperature readings through a simple 1-Wire communication interface. Only one data line and ground connection are required, significantly simplifying wiring and allowing multiple sensors to operate on the same communication bus. Supporting operating voltages from 3.0V to 5.5V, the sensor is compatible with a wide range of development boards and embedded systems. It is an excellent choice for water quality monitoring, smart agriculture, aquaculture, environmental monitoring, and IoT-based temperature measurement projects.
