DS18B20 digitale temperatuursensorsonde – Programmeerbaar

Dit is een op maat gemaakte 1-draads en waterdichte versie van de DS18B20-sensor. Handig voor als je iets ver weg moet meten, of in natte omstandigheden. Using the digital temperature sensor DS18B20 from Dallas Semiconductor and the high thermal conductivity sealant potting, the temperature sensor is highly sensitive and has a small temperature delay. De temperatuursensor ondersteunt de “1-Draad” interface (1-Draad), en het meettemperatuurbereik is -55℃~+125℃. In the range of -10℃~+85℃, the accuracy is plus or minus 0.5 degrees Celsius. The field temperature is directly transmitted in a digital way of “1-Draad”, which greatly improves the anti-interference ability of the system. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.

It is suitable for field temperature measurement in harsh environments. DS18B20 digital temperature sensors all have unique numbers, and the temperature acquisition equipment uses the number to identify the corresponding temperature sensor.

The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor. We don’t have a detailed tutorial up yet but you can get started by using the Dallas Temperature Control Arduino library which requires also the OneWire Library.
