Can also do…..
String quotes = String(34);
data7 = String(quotes + data0 + data1 + data2 + data3 + data4 + data5 + data6 + data8 + quotes); -
Rick Vogel posted a new activity comment 3 years, 1 month ago
data7 = String(‘ ” ‘ + data0 + data1 + data2 + data3 + data4 + data5 + data6 + data8 + ‘ ” ‘);
for visual purposes I added a space between the single quotes and the double quote. you probably want to remove those extra spaces in the sketch

I had a recent question from a person stationed in Alaska regarding ice thickness measurement. They already perform the drill and measure method, but was wondering is there was any hand held instruments or other smaller device that can measure without the need for drilling through the ice. Please let me know if anyone has heard of such a thing. Thanks!!

Distance is possibly an issue if the wiring to logger isn’t short. For the enclosure application, I thought about dropping a small teensyLC in the base with TTL/RS232 interface so that a serial connection could be made from enclosure to logger. Teensy would handle all the sensor data requests and then just feed a csv over TTL or RS232 depending on…[Read more]

What’s the supply voltage (Vcc) of this board? I’m wondering if you designed it for a 5-volt I2C bus like the Uno, or if it’ll work with 3.3v systems, like the Mayfly or Raspberry Pi.

I’m not sure if the questions regarding the 4-20mA circuit would be sufficed by something like this?
Very good info on using RS-485 with arduino platforms is located here:

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.

Rick Vogel replied to the topic Datalogger build in the forum Other Data Loggers 5 years, 7 months ago
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=15I 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]

Steve, when I first read your comment I was a little confused. I haven’t used the stalker board before, but I was under the impression that it was a ATmega2560 and not a 328P. I couldn’t figure out why you had code constraints…….
I spoke offline with Steve Hicks about the 2560 logger board I had done. If the community thought it would be…[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]

Anybody aware of a source for probe style enclosure that could have filter cap screwed on top. I would like to put my sensor board in a probe housing but can’t seem to find that type of enclosure around anywhere.
-
Hi Rick, I’m not sure if this is what you’re looking for since I can’t tell if you’re looking for a housing for your sensor or just the board itself. Check out Atlas Scientific…they have some sensor pipe fittings that can be screwed on to PVC pipes that house sensor heads:

In particular,…[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]

Rick Vogel started the topic Soil Temperature Probe in the forum Environmental Sensors 5 years, 8 months ago
Has anyone come across a single probe with soil temperature sensors at various depths within the probe? I know there are numerous soil temp/moisture sensors for depths close to surface, but looking for one that might have 5 to 6 different depths within a single probe.
Looking to measure depths of 4, 8, 12, 20 and 40″

By the way, as far as enclosures go. I’ve had great luck, even when it comes to customization using TEKO, PacTec and Polycase.
