Detection of DS18B20, arduino Mega. I just bought a DS18B20 temperature sensor. // You can have more than one DS18B20 on the same bus. but a guess is that you are not sending the required instruction.What was alluding to is the "by index" polling in the above link. Today I'm going to show you how to use digital temperature sensor with Arduino, so you can measure the temperature of the air, liquids like water and the temperature of the ground.is 1-Wire digital temperature sensor from Maxim IC.

Please help
