EASY INTEGRATION & WIDE COMPATIBILITY: Get your projects up and running quickly with these versatile probes. Featuring a simple 3-wire interface with clear color-coding (Red: VCC, Yellow: DATA, Black: GND), they are fully compatible with popular microcontroller platforms including Arduino, Raspberry Pi, ESP8266, and ESP32, making them perfect for hobbyists and professionals alike. ACCURATE & ADJUSTABLE DIGITAL SENSING: Measure with confidence across a wide temperature range from -55°C to +125°C. Each sensor features a user-configurable resolution from 9 to 12 bits, allowing you to balance measurement speed and precision to perfectly suit your application's requirements, from fast environmental checks to high-accuracy data logging. ROBUST WATERPROOF & STAINLESS STEEL DESIGN: Built to last, each probe is encapsulated in a high-quality, waterproof stainless steel tube, protecting the sensor from moisture and corrosion. The durable 1-meter cable provides ample length for flexible placement, ideal for measuring liquid temperatures, monitoring soil conditions, or deploying in outdoor and humid environments. FLEXIBLE POWER & ONE-WIRE INTERFACE: Designed for versatility, these sensors operate on a wide power supply range of 3.0V to 5.5V, ensuring compatibility with both 3.3V and 5V logic level systems. The 1-Wire communication protocol allows multiple sensors to be connected on a single data line, simplifying wiring for complex projects. For stable operation, a 4.7k Ohm pull-up resistor between DATA and VCC is recommended (resistor not included). COMPLETE 5-PACK FOR MULTIPLE PROJECTS: This value pack includes five DS18B20 temperature sensor probes, providing excellent value for projects requiring multiple measurement points or for stocking your electronics workbench. We provide comprehensive after-sales support: complete digital documentation including user guides and technical references is available through our store customer service, and our support team is ready to assist with installation, programming, and troubleshooting to help you get started quickly.
