    I download data every couple of months, or as needed. It’s a pain, and I inevitably have overlap of data to clean up.

    My current plan allows for 3 month’s data storage (Maker plan), but I notice on the current pricing only 1 month of storage is provided. I’ll get the good news at plan renewal time I’m sure!

    I’ll have a look at arduino cloud /…[Read more]

    Hi Neil

    I had a go at arduino cloud about a year ago.

    For price/configurability I ended up switching to Blynk. I’ve had 5 arduino MKR GSM boards function flawlessly for the past year. I think Blynk is aimed at developers, but there was enough sample code for me to get the board running .

    That said, the current arduino pricing looks good.

    I’ve…[Read more]

  • Hi Karl

    Have you had a look at maxbotix? Not sure if they do a 150m ranging sensor – could you mount the sensor on a rod and insert that to say 140m or is the fluctuation in level too much?

    This video also presents a range of options, more on the diy side…

  • Thanks for the feedback

    Funny you should mention rocket scream, I’ve just had a few red comet esp32s delivered. They promise low power consumption and solar charging for lifepo4. I’m hoping to replace a rather bulky 12V panel and battery system with the red comet and a single cell 26650 lifepo4 (see…[Read more]

  • Hi all

     

    Just wanted to get your thoughts or options for lifepo4 power for monitoring stations. First off, I generally use an arduino pro mini 3.3V for switching on/off the main logging system and in sleep mode the pro mini consumes ~50 uA. I’ve also just got a hold of the rocket stream mini ultra which promises 4 uA sleep current, lets see…[Read more]

  • Hi Neil

    Thanks for the feedback. So I guess a separate sensor housed in the same box as the mkr1400 would be useful. That’s on the (long) list of improvements!

    I’ll post some actual data from the piezometer in the next couple of weeks.

    Cheers

  • Hello

    I thought I would share my experience of using the DF robot gravity industrial level sensor (KIT 0139), as there have been a few posts about it.

    I’ve connected this to an Arduino MKR1400 GSM board via an ADS1115 16-bit ADC.

    The results initially were stable enough. I put the sensor in a covered bucket of water (static level) and checked…[Read more]
