I have a water carried floor heating system. The system have a cabinet where the loops are splitted. In total I have 10 forward/return loops and I would want to measure them all (in total 20 1-wire sensors).
I will place a Arduino in the cabinet, so cable length will be maximum 20 metres.
How many 1-wire sensor would be possible to hockup to a Maxim DS2482-100 over I2C? Would I need multiple DS2482-100 to make it?
Not necessarily a daisy chain. Something like this is OK as well:
Capacitors on power line (10nf-100nf) is not mandatory but helps for more reliable communications. You can put them where you connecting "branches" to a bus.
Alright, but my arduino will be < 1 meter away from the sensors, so all sensors will have same length wire <1 så asically the cap will be placed on the arduino,, I guess the cap won't aplliable on this setup.
