I have been running Mayfly successful for several months now for water level measurment (Maxbotix). Very nice platform! Recently, I installed one in the field. Anyone can advise me a method for making a “DIY staff gauge” for instaling besides my sensor? I want to learn to make them myself so I can customize the marking, and, I want to…[Read more]

The error comes because I have not installed the library “Sodaq_PcInt_Mod.h” and “SoftwareSerialMod.h”.

When checking the Github files, I see “EnviroDIY_SoftwareSerial_PCINT12@…” with indication of “Renamed SoftwareSerialMod”. Could anyhow tell…[Read more]

I have a maxbotix ultrasoon sensor connected to the mayfly, and energy is coming from battery and small solar panel included in the kit (I will buy a larger battery and solar panel). It functions well, thanks to the help of Shannon. My final objective, however, is to monitoring the water level in several water tanks (>10) in a large…[Read more]

It uses 5V as input. If I understand well, I can not use with Mayfly, as the maximum output voltage is 3.3V? From other posts on this forum, I saw they were…[Read more]

I have bought a Particle Electron for remote monitoring via mobile phone network. I also have a Mayfly to locally record the data. Is there a way I can ´combine´ Particle Electron and Mayfly? For me, the advantage of Particle is that is already comes with a chip that operates in Latin A…[Read more]

1) What solar panel are you using? The solar panel that comes with the Mayfly is much smaller.
2) Is it acustic material that you use to fill up the space in the box? Has it any other function?

With friendly greetings,

Arnoud

Thanks for the info. Does the cable of the Adafruit solar panel need some adjustment (or additional jack), or one can plug it in directly?

With friendly greetings,

Arnoud

Some weeks ago, Arduino/Siemens presented at the Rome Maker fair a “multi-task open Industrial IoT gateway” developed by Siemens and compatible with Arduino and related shields. (https://www.rs-online.com/designspark/simatic-iot2020) They promote its robustness (heat, dust, outdoor, etc.), its certification and low price. My first rea…[Read more]

Indeed, I was probably erroneously connecting the PWM output (2) instead of the serial (5) to the Mayfly. I will give it a try this week and keep you informed. Thanks for the help…

I have the same set-up of Maxbotix sonar with Mayfly as Steven. I did some trials first with my arduino and analog signal reading which was succesfull.

Now I trying the serial code available on the enviroDIY website, but readings are 0 mm. I hope following questions may help me to get succesfull measurements:
1) In the code the pin 5…[Read more]

On the short-term, I will be performing a Rhodamine WT experiment for which I will be using the Cyclops sensor (3-15 VDC >100 mA INPUT and 0-5 VDC output) of turner design. If I understand well, the Mayfly is not the best option for this type of analog sensor, because of the risk of having an input signal of the sensor to the…[Read more]
