Product Description:
YJJ DS18B20 Digital Temperature Sensor Probe for Water Temperature Detection With Stainless Steel Waterproof Housing
Features:
Using the digital temperature sensor DS18B20, with a high thermal conductivity sealing
gel encapsulation, ensures the high sensitivity and extremely small temperature delay of the temperature sensor. This temperature sensor supports the "one-wire bus" interface (1-Wire), with a temperature measurement range of -55°C to +125°C. Within the range of -10°C to +85°C, the accuracy is ±0.5°C. The on-site temperature is directly transmitted in digital form via the "one-wire bus", significantly improving the system's anti-interference ability. It is suitable for on-site temperature measurement in harsh environments. The DS18B20 digital temperature sensor all have a unique identifier, and the temperature acquisition device identifies the corresponding temperature sensor through the identifier. Sensor
The length of the lead wire can be customized according to the user's requirements.
