GX18B20 is a temperature sensor with "one-wire bus" interface. The unique and economical characteristics of the first-line bus make it easy for users to set up sensor networks and introduce new concepts for the construction of measurement systems.

The measuring temperature range is -55 +125 C, and the accuracy is +0.3 C in the range of -10 +85. The accuracy of DS1822 is (+2) C. The field temperature is transmitted directly by the "one-wire bus" digital mode, which greatly improves the anti-interference ability of the system. Suitable for field temperature measurement in harsh environment, such as environmental control, equipment or process control, temperature measurement consumer electronic products, etc. Unlike the previous generation, the new product supports the voltage range of 3V to 5.5V, which makes the system design more flexible and convenient. And the new generation is cheaper and smaller.
