Hey there. long time to see.
Got some quesitons for ya.
Looking into making a controller of sorts with PIC's or PLC's.
want to monitor pH, Salinity, Temp and anything else I can come up with. Those four(two pH's, tank and effluent) I want to send to an 8 bit ADC PCI card inmy puter to log the data. Was thinking instrumentation amps to amplify and clean the signal as they will all be low voltage signals(mV)
the temp signal I will aslo send to a bunch of PIC's to shut off/turn on various pieces of equipment. fans, lighting heaters etc.
any ideas?
