About DS18B20 miss counted sensor

hi, I am using multiple DS18B20 library on a project. I always have problem to read out correct count of sensors. For example, I have 5 sensors, but it only reads out 3 values. Does anyone know what the problem is? how should I solve the problem. I know the function, begin( ), counts the number for us. Is there any problem in this function? or any problem in OneWire library?

I moved 4 posts to an existing topic: Getting correct address of DS18B20

Considering the two topics are about the same issue, it’s wiser to keep it together to prevent information from spreading, and questions having to be answered multiple times.
