Adafruit High Temp Waterproof DS18B20 Digital Temperature Sensor

This pre-wired, waterproof DS18B20 sensor with PTFE wire cable excels in precision temperature measurement in challenging conditions, supporting ranges up to 125°C. Unlike PVC versions, its design resists high temperatures, although it's unsuitable for corrosive environments.

With digital signal transmission, experience no degradation over long distances. Accurate to ±0.5°C, the sensor delivers up to 12 bits of precision, capable of interfacing with microcontrollers using a single digital pin. Uniquely identified by a 64-bit factory-burned ID, multiple sensors can share the same pin effortlessly.

Optimized for 3.0-5.0V systems, it requires a 4.7k resistor for proper operation. While the Dallas 1-Wire protocol adds complexity requiring library support, resources are available for CircuitPython and Python. For simpler analog alternatives, consider the TMP36.
