DS18B20 Temperature Sensor

The DS18B20 is a high-precision digital thermometer that provides 9-bit to 12-bit Celsius temperature readings. It communicates over a single 1-Wire bus, requiring only one data line (and ground) for communication with a microcontroller, which simplifies wiring significantly. This sensor features a unique 64-bit serial code stored in ROM, allowing multiple sensors to share the same bus. It has a wide operating temperature range of -55°C to +125°C and an accuracy of up to ±0.5°C. The sensor is commonly used in HVAC systems, industrial temperature monitoring, and consumer electronics. Its waterproof variant makes it suitable for liquid temperature measurement. Choose this sensor for its reliability, low power consumption, and ease of integration with popular development boards like Arduino and ESP32.
