  neilh20 replied to the topic Adding a new modbus sensor using current ones as inspiration. in the forum Environmental Sensors 2 years, 5 months ago

  Hello Erik, sounds like you are on the path to learning Cpp.  One issue to keep in mind is that the code is what happens, the reality check, the documentation is for readability.  You may want to be list what gas sensor you are looking at for the max help.

  So I don’t follow your question  – where do you get the code snippet from the first se…[Read more]

  Erik G started the topic Adding a new modbus sensor using current ones as inspiration. in the forum Environmental Sensors 2 years, 5 months ago

  I would like to add a gas sensor which communicates over RS485 to work with the modular sensor library but having the normal issues with me lacking the programming skills needed.

  I have used the Yosemitech and Keller librarys as a template and tried to make it as basic as possible.

  When checking the example code for the modbus sensors i get…[Read more]

  Thanks for the followup.  Plugging an EnviroDIY sim7080 LTE bee board into one of the old Digi bee adapter boards will definitely cause problems, since there are different pinouts for the 2 cell modules, as well as different supply voltages provided to the pins, which could damage the sim7080 bee.  Also note that upgrading a Mayfly board from a D…[Read more]

  Thanks all for the feedback. I went out to the site yesterday. One of our staff had switched out a Digi modem for an EnviroDIY modem a while back and plugged the EnviroDIY modem into the Digi adapter board. I wonder if that had something to do with the issue?

  I went ahead and switched out the logger, battery and modem as I didn’t have time to…[Read more]

  Shannon – thanks for your thoughtful reply.  I’m sure I’ll be able to find the problem now.  Answering your questions:

  1. I’m not switching D22 on.
  2. Humidity is a possibility. I’ll look for corrosion and add desiccant .
  3. I’ve had ants at another location but not this one…yet.
  4. I’ll make some tests as you suggest to isolate the problem.  It mi…

  neilh20 replied to the topic Mayfly 1.1 powering review & analysis in the forum Mayfly Data Logger 2 years, 5 months ago

  For  powering I am using the new Solar2 connector.

  It requires a very precise diameter solid core wire – and took me some time to find it as old fashioned “Bell Wire” 20AWG, which I got from local Lowes store.

  The needs to be – 20-26 AWG solid core. It also needs exactly matched wire strippers. If the wire strippers are too small a dia, its…[Read more]

  An update on measuring battery voltage. I’ve purchased a number of Mayfly1.1 for a project. And on testing one of this batch, the noise level of measuring LiPo is better – which is great.  The noise level of resistors is part of their  specification, or it might be just luck in this case.  Often a batch of noisy resistors is because the ma…[Read more]

  Hi Jake, my take is its complex to be able to decode why MMW isn’t showing data ~ it needs a system look, location aspects (solar looks excellent) ,  maintenance inspection of site,  reliability of hardware/battery/mechanics reliability of software on the Mayfly, reliability of software at MMW

  It would be useful to know your configuration i…[Read more]
