Hi All,
To some extent this follows from thread: *Reliability and
Robustness of the DS2482-100 or DS2482-800*
I've been using a couple of Raspberry Pi's (RPi 1 Model A+) to
manage the temperature, humidity and lighting in a terrarium since
2014/2015. One Pi is in active use while the other is used as a
development platform to try things out on. Overall I'm impressed by how
much one can do without spending a fortune and I'm quite keen to explore
further.
One thing which always bothered me with the Pi's is the SD card.
I've had a few corruptions (all power supply related). Even with a clean
and stable supply I am still doubtful if one can achieve "industrial
grade" reliability if using SD cards. So I'm now looking for other
microcontroller options to control my 1-wire based system as I'm
intending to extend management to my greenhouses where reliability is
more important.
Options I have looked at so far include the Arduino (Uno, Zero or
DUE) and the ESP32. Haven't fully explored the latter but it seems to
have an incredible number of interfaces. I'm quite impressed by the
Arduino - it's simple, there's a big choice of units and it's easily
extensible (with a lot of pre-built modules available). My design will
involve power switching and (ideally) more than one 1-wire bus (so a
DS2482-100 is likely to be involved). The system will also interface to
my network for monitoring and management.
What are your opinions re. suitable microcontrollers where
reliability and ease of extensibility are requirements.
