Jim Moore started the topic Case for Lower Threshold Voltage on Mayfly Stations in the forum Mayfly Data Logger 1 year, 5 months ago
I have attached a document I wrote up on some battery testing I have been doing. My conclusion is that a modem cutoff voltage 3.3 Volts shouldbe used rather than the 3.55 that is in the code I used for my LEC Sensor stations. I would appreciate any comments and explanations of of some open questions.

Jim Moore replied to the topic Atlas Scientific Logger – Sleep between readings in the forum Mayfly Data Logger 1 year, 9 months ago
I am using the same hardware with my Low Cost EC stations which is set up for UART mode but I have since upgraded to I2C mode when I added the 2G modems. I am using the sensorex probe for the EZO EC which has an integral RTD which I read thru the analog input. I think its only about a $30 premium for the the RTD option. Maybe there are som…[Read more]

Thanks for the info Shannon. I will check out the GPRSbee and sd card to see if they are the cause of the 2.4 mA draw when in sleep mode. I’ll try a new Mayfly board next.

Jim Moore replied to the topic Monitoring power consumption in the forum Mayfly Data Logger 1 year, 10 months ago
I checked my GMI_EC5 station that I mentioned above that was not keeping up and I measured about 2.4 mA current draw when the mayfly is in sleep mode. I thought it should be close to zero when in sleep mode.
Any thoughts Shannon?

Jim Moore replied to the topic Monitoring power consumption in the forum Mayfly Data Logger 1 year, 10 months ago
I have the same issue. I have my LEC stations (GMI_ECxx) running with 2G cell service and I did have one station that the solar charge chip failed and caused battery to drop below the 3.55 volt threshold for upload. However GMI_EC5 seems to be getting a charge during the day but is still not keeping up. I attached a screen from MMW…[Read more]

Jim Moore replied to the topic Buy 20-25 Mayfly Data Loggers and Proto Shields in the forum Mayfly Data Logger 1 year, 10 months ago
I checked Amazon and finally discovered that “envirodiy mayfly protoshield” works for a search. Did not have envirodiy in my search query.
I just bought the last one so guess time to restock

I just checked Amazon and no Protoshields showing. I guess shipment processing isn’t one day turnaround! -

Hi Sara @srgdamiano
I haven’t used PIO for several months but in preparation for the transition from 2G to 4G I launched PIO this week and it apparently did an upgrade and now my code won’t load.
I get the following error:
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00
PIO is currently core 4.3.4 and home 3.2.3

Since it’s not a MMW issue should I move my technical questions back to my original post on “infrastructure and equipment” forum?

Jim Moore replied to the topic MMW Data Outage? in the forum Monitor My Watershed 2 years, 1 month ago
Thanks for the update, Shannon. Are there any plans to buy a quantity of 4G hardware in the expectation of a discount? I will need at least 8 and would be glad to help out where needed.

Thanks Chuck for getting my Sensorex RTD voltage divider output converted to °C. I plan to leave the EC as the raw value from the AtlasScientific EZO circuit. Attached is the code addition to DRWI_CitSci.ino to get the Sensorex probe data published to MonMW:

Thanks for the posting. In N California I’ve had a squirrel chew through some power wiring at one site. I think in the end it was to do some armored flexible PVC tubing.
