Description

It is a hardwired version-sealed Sensor DS18B20, which handy if you need to perform a measurement of remote temperature or in wet conditions. Although the sensor can measure up to 125 ° C, we recommend that you limit yourself to 100 ° C. Since this sensor is digital, you can use it over a long distance without deterioration of information. This One Wire sensor is accurate to 0.5 ° C on a part of the measuring range with a scanning on 12 from bits of internal CANCER. It works on most of the microcontroller and requires only a single pin, you can m ^ connect me several on the same pin since each sensor has a unique 64-bit written in hard at the factory address. This pateur works as well in 3, 3V and 5V.

The only downside it ets this sensor uses protocol Dallas 1-wire which is quite complex, but heuresusement the library exist already for Arduino.

The sensor is sold with a resistance of 4, 7kohm to serve pull-up between the line of DATA and the VCC.

For use on arduino, we recommend the bookstore Dallas Temperature Control Librarywhich requires the library OneWire Library.
