Introducing the Lonely Binary Digital Temperature Sensor DS18B20. This pre-wired and waterproofed sensor is perfect for measuring temperature in distant or wet conditions. With a temperature tolerance of up to 125°C and a PVC jacketed cable, it's designed to handle various environments while maintaining accuracy.

The DS18B20 is a digital sensor, ensuring reliable signal transmission without degradation even over long distances. With a precision of ±0.5°C over a wide range, it delivers accurate temperature readings for your projects. The onboard digital-to-analog converter provides up to 12 bits of precision, enabling detailed measurements.

Compatibility is a breeze with the DS18B20. It works seamlessly with any microcontroller using a single digital pin. Plus, each sensor has a unique 64-bit ID burned at the factory, allowing multiple sensors to be connected to the same pin without confusion.

Operating at 3.0-5.0V, this versatile sensor adapts to your preferred voltage system. Whether you're monitoring temperatures for scientific experiments or building smart home devices, the Lonely Binary DS18B20 is your reliable companion.

To make your experience even better, we include 4.7k resistors with the sensor. These resistors serve as a pullup from the DATA to VCC line, ensuring smooth operation without the need for additional components.
