should maintain time as long at vBatt on the RTC is good……although plugging and unplugging electronics can do crazy things sometimes. At least now you have a quick way to set the time should you need to.

Try this latest one if you have issues. Setting the time within Arduino Serial monitor with T0045….. will still work, but if you are in hyperterm or putty just hit the “?” symbol and it should bring up a menu for you to modify the time manually and step you through the process. If you have issues just let me know and I’ll help you get through.…[Read more]

Brandon,
Open up the Serial terminal within the Arduino IDE and perform the following:

Send Time as T, sec(00-07), min, hr, dayOfWeek, dayOfMonth, month, year.
example: T0045073071015 Send/Enter
//sec=00, min=45, hr=07, dayofweek=3, dayofMonth=07, month=10, year=15

I forgot that using Putty or HyperTerm this won’t work because they send chars…[Read more]

Brandon,
I took a look at your code. Not sure why the clock is doing that to you, but Rene could be correct. I’ve not had a clock do that to me before so I couldn’t personally confirm.

I don’t typically use the RTC library as I only need a couple of functions (set time and get time) so I just put the operations within the main sketch. If you…[Read more]

Stroud has a great SDI-12 Arduino interface. it only works with Atmega 328P based Arduinos though.

mathew, just so you are aware……the SDI-12 library will work on the Mega2560 as well. I’m using it right now to pull SDI-12 data from a Sutron Rain Weight gauge. You can only use pins that are set up for digitalPinToPCMSK calls if I remember…[Read more]

We actually built 3 “in-house” prototypes that utilized different style thermistors(rivet style, tab w/ screw, etc…) and housed them in a single pvc pipe that was capped. We filled the pvc with spray foam to try and deal with moisture issues. All wires from thermistor were ran to a campbell datalogger at our Sterling, VA test facility and all…[Read more]
