Identification of temperature Sensors DS18B20


  • I am using three Blue Sea Systems mini bus bars to connect 8 sensors to an ABMS. I have tested up to two on the bench, and they show properly in the interface. Short of using some heat or cold to trigger a response, is there a way to identify or assign a number to each sensor, thereby knowing which part of the battery box corresponds to what temperature? Also, is the assignment in the interface subject to the vagaries of chance each time the system is booted? Or, once each sensor is identified, will it always show up in the interface with the same ID? For example, if I place a sensor on cell 1 and it shows as number 4 in the interface, next time I boot the system, will it again show as number 4, or will it be assigned another ID in the interface every time the system is restarted?



  • Hey Stephano,

    The way 1Wire networks work is they use the network ID number as the reference so once you thermo cycle them you can sort them by cell #, as the ID number is not usually written on them.
