Sonde de capteur de température numérique DS18B20 – Programmable

Il s'agit d'une version personnalisée à 1 fil et étanche du capteur DS18B20.. Pratique lorsque vous devez mesurer quelque chose à distance, ou dans des conditions humides. 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. Le capteur de température prend en charge le “1-Fil” interface (1-Fil), et la plage de température de mesure est de -55 ℃ ~ + 125 ℃. In the range of -10℃~+85℃, the accuracy is plus or minus 0.5 degré Celsius. The field temperature is directly transmitted in a digital way of “1-Fil”, ce qui améliore considérablement la capacité anti-interférence du système. 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.

Capteur de température numérique DS18B20, tube en acier inoxydable OD 6x30mm, câble UL2547

DS18B20 temperature sensor -55℃ ~ +125℃ Power supply 3.0V-5.5V

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.
