  @khaase great to hear  – do you have a pn for the cap – be interested see what the internal ESR is.

  Seems to me a way to monitor the battery for maximum life is to read the voltage unloaded, and then again when it is loaded.  The capacitor moderates the voltage reading, but still droops. So it would be how much droop (lack of charging from high i…[Read more]

  Khaase replied to the topic Mayfly 1.1 Bootloader Burning? in the forum Mayfly Data Logger 1 years, 10 months ago

  An update: I got the Tag Connect socket and it works fine on my Pololu Atmel ICSP programmer, and using it burning bootloaders and program Mayflys is fast and fun.

  I am still sorting through my test results and will probably have to do a new battery of tests with an external datalogger because the internal ADC gets confused by low voltages, but…[Read more]

  So far, your super-capacitor idea is holding up pretty well for me. A 100 uF capacitor buffered voltage sag to a degree, but the 10,000 uF supercap (1/10 the voltage rating and 1/2 the size) gets our setup able to use any given battery voltage measurement without having to consider if the sensors are on or not. (I want to write “Battery voltage…[Read more]

  neilh20 replied to the topic SDI-12 Library in the forum Other Data Loggers 1 years, 10 months ago

  @vogelrnws I had been looking at porting it to another processor and been using it and digging into the code. I’ve looked at some of the RP2040, but I’m cautious about its ability to go into low power – but haven’t looked at it in depth.

  The SDI-12 lib uses a software based UART – running at 1200Baud, so 1200Baud is pretty slow and it does handle…[Read more]

  Has anyone looked to see if the SDI-12 library could be ported to the new RP2040 chip. Maybe that already works in its existing state, but I haven’t see it mentioned anywhere. This is the new IC that runs the RPi Pico and can be used via the Arduino language.

  neilh20 replied to the topic Arduino NB-IoT for ISCO autosampler in the forum Infrastructure and Equipment 1 years, 10 months ago

  @hannahlb if I understand you – you have 4 geographically distributed ISCO samplers (say more than 100m apart) and you would like to trigger them  when a threshold is exceeded from a Solinst level sensor.  The trigger would be communicated via messages on the telemetry NB-iot?

  Probably the best way to think about it is in stages

  1) figure if t…[Read more]

  Hannah,

  I use Campbell dataloggers (CR800) to collect and send data from ISCO auto samplers to a database. The Campbell datalogger program also has the capability to accumulate stormwater flow data and initiate flow paced sample collection with the samplers via a SampleRequest command. I haven’t connected an ISCO 6712 to an Arduino but I’m…[Read more]

  Hannah Lehnhart-Barnett started the topic Arduino NB-IoT for ISCO autosampler in the forum Infrastructure and Equipment 1 years, 10 months ago

  Hi all,

  I’m new to this community and am currently trying to figure out how best to connect an ISCO 6712 autosampler to an Arduino-based narrowband Internet-of-Things (NB-IoT) module. The aim is to create a node network of 4 autosamplers which will trigger simultaneously during events based on a water level threshold measured using the Solinst…[Read more]

  Hi Sara,

  Here’s an example: http://18.117.19.92:8080/wofpy/rest/1_1/GetValuesForASite?site=envirodiy:BCGC2S&startDate=2022-12-09T00:00:00&endDate=2022-12-09T23:59:00

  Yes, I’d like to regularly poll the system. I’ll send an email.
