        I am very new to this type of datalogging and building (just this week while visiting SWRC). I am not really sure where to start when it comes it to which board to purchase. I do know that I need an o

          Hello Brandon
          Can you say a little about your application/project – is it something you are collecting data to supply to others or a kick-off learning project, how urgent is the project, is it o

              Hi neilh

              This project is a dual purpose in that primarily will be a kick-off learning tool but also be used by local high school students. It is an outdoor project with no power source other than ba

                  Wow Brandon, sounds like a great project. I’ve just got back from a music festival – and have a whole pile of work to get through – but hopefully can get back tomorrow with some ide

                    Hey neilh

                    Ultimately that is the direction I would like to take this. I first want to build a complete setup to have it up and running then have it broken up in ‘pieces’ for the students.

                      Hi Brandon,
                      I’d Be interested in who your contact is at SWRC that you heard it from.

                      I’d say if you want to start monitoring ASAP you’ll need to buy the “value added” sy

                    Not sure if SDI12 is where you’re going, there are DIY options too.

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

                        Hi all

                        I am finally working on a system. I have an Arduino Mega 2560 – R3, the Adafruit Datalogging SD Shield, and just a DS18B20 temperature sensor (waterproof with 3 wires using a 4.7 ohm res

                          Hi Brandon,

                          Have you checked the battery for battery health? While the Arduino is disconnected, connect one probe of your multimeter to the top of the battery, and one to the GND breakout on the data

                            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.

                              The battery is brand new but I did confirm it has the correct voltage.

                              How would I go about forcing the time set on the RTC now? I tried the code you provided as is and t

                                  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

                                  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

                                    Thanks for the info. I believe this is working. I am having power issues now though too so I can’t be sure. The dc jack will not give consistent power. I may have fried something when we t

                                      Your method does work for the most part. However, when I moved the adafruit sd/rtc shield to another board I had to send the time to it again. Should the rtc maintain the time once set since

                                        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 sho

                                          FWIW, in the past I’ve had a few times where the DS1307 clock on the Adafruit shield would reset to some random time in the past or sometimes even in the future. If I remember right, I think it
