@rogers1313 gosh its all depends on the software you are using – what’s the version of software and the source. Since its open source software and hardware, and you can look at the software – its possible to guestimate those answers. Then since its software that causes the most power usage, it needs testing.
For a turnkey system, assembled off…[Read more]

Your questions are all very subjective to a variety of operating conditions, so I can only give you some broad estimates of what we’ve experienced with the 300+ stations we’ve installed and maintained.
We typically put a 4400mah Lipo battery on the Mayfly boards because on standard logger configuration, they can be charged fully by a 3.5w or 5w…[Read more]

You’re right, you correctly have your sensor’s signal white wire connected to the Grove cable white wire, which goes to the AA1 pin of the Aux Analog grove jack, so you can disregard my suggestion to change the ADS1115 code to adc0, and just leave those two lines as they were, using adc1.

Thank you for your reply! That definitely helped. I think the only thing I’m still confused on is the output channel. You mentioned that the white wire in the uppermost grove jack is connected to analog channel zero, but when I look at the board, the label next to that wire is AA1. If you could clear that up for me that would be great. Thanks for the help!

We are installing a new Mayfly 1.1 data logger with the LIPO 4400mah battery, LTE Bee cell modem, and a ETFE 5W 6V solar panel, Hydros21 CTD sensor taking data at 15 minute data taking intervals.
My questions are as follows:
With this setup what is the amp hour usage of the Mayfly 1.1 datalogger using the LTE Bee cell modem and the Hydros…[Read more]

You’d have to check with Meter Group to find out what the sensor communication protocol is. There’s nothing on their website to indicate what sort of output it has.

Shannon Hicks replied to the topic Hyrdos 21 Gen2 – Can't Change Address in the forum Environmental Sensors 1 years, 5 months ago
If you’re able to swap out a Hydros21 manufactured in 2022 with your hardware and everything works fine, but sensors from 2023 aren’t working, then it’s possible that they’ve made another design change that requires some tweaking of the ModularSensors code library to make them work correctly. We’ve had a report of one other person having trouble…[Read more]

First you should attach the sensor’s clear wire to the GND pin of the screw terminal board along with the black wire.
Second, the sensor needs at least 5 volts of excitation power, and the jumper setting of the Aux Analog Grove jacks in your photo is set to the default 3v position. You need to move that jumper to the 5v position. See the s…[Read more]

I am trying to get shortwave radiation readings from an Apogee pyranometer (SP-212-SS model). I am new to electronics and microcontrollers, so there could be a lot of places I am going wrong here. I am using a Mayfly version 1.1 as the data logger. To connect the sensor, I am using the Aux Analog grove terminals. I’ve attached a picture of my…[Read more]
