Multiple DS18B20 temperature sensors with Arduino

In this video, we will learn how to connect / interface/ use more then one DS18B20 temperature sensor ( IC ) with the same pin of Arduino Uno. The DS18B20 has unique 64 bit address code. So we can easily get sensor data of a particular DS18B20 sensor by using its address. Arduino code for the sensor is also shown in the videos. You can use the same code for Arduino Mega also.

dear sir, do y think we can plot different temp with two sensors + arduino on matlab?

Hi, i like the code as it is nice and short, what i would like to know how would i use this code that has extracted the address to operate more than one LED each with it's own temperature sensor connected to it . Normally i would use the which i would use to work the one LED. Thanks in advance. i looked all over cant find an example.

@DPV Technology, code link is not working.

Great video thank you for sharing, can you use the serial unique address of the temp. sensor alone <I mean to use led for example same pin ?

Why my address device won't show up in the monitor?

what am i gonna do when i want temperature ranges in ds18b20 using stepper motor
