DS18B20 Waterproof Digital Temperature Sensor Probe
The DS18B20 Waterproof Digital Temperature Sensor Probe is a digital temperature sensor with a stainless-steel waterproof probe and approximately 1-meter cable. It communicates with a microcontroller using the 1-Wire protocol, requiring only one data line for communication. Directronics It can measure temperatures from approximately -55°C to +125°C, with around ±0.5°C accuracy between -10°C and +85°C and selectable 9–12-bit resolution. Each sensor has a unique 64-bit identification code, allowing multiple DS18B20 sensors to share the same data bus. DSMonline Ideal for Arduino, ESP32, ESP8266, Raspberry Pi, aquarium monitoring, weather stations, agriculture, water-temperature monitoring, robotics and IoT projects.
