I'm a total novice at Arduino and am looking for some feedback/advice on the best way to record ASCII data output from an RS232 port onto an SD card. I think this can be done with an Arduino but have a few questions before I sink my teeth in:
The instrument (an analytical balance) outputs ASCII-formatted data from an RS232 port at ~1 Hz but does not output a time stamp. Is there a way to write this ASCII data to an Arduino while simultaneously recording a time stamp from the Arduino?
The balance will be deployed overnight so 1 Hz data is overkill for this purpose. Is there a tutorial that goes through how to automatically average the 1 Hz data to a 10 min average?
Someone suggested I use a Raspberry Pi instead - would this be easier? Are there any other platforms/methods that would be easier?
CONTEXT: the ultimate goal is to create a dewfall meter that can accurately and precisely measure the mass of dew as it accumulates overnight. On top of the balance is a tray containing artificial turf so as dew collects on the turf the balance will detect the additional mass.
