The packet design is not optimally designed for wireless conditions, the thingspeak packets are much lighter. If your site is on the edge of the wireless range,  which varies a lot of with weather conditions, its going to have more trouble with…[Read more]

The reliable bit – as in all engineering – is to add a buffer for real world component variations and t…[Read more]

For my systems I look to have it last 14days before it reaches 3.8V and it is a difficult target unless its being tested for and the time taken on the radio is also characterized.

I see the issue is how to keep the sensor readings delivered reliably while there is enough power, and then when…[Read more]

It very much looks like up to early October the solar was delivering enough power for the system.

Then with the seasons solar changing, the solar panel aspect is not delivering the power needed

What I would recommend is a) need to charge up the internal LiIon 4.4Ahr battery

  1. …

It very much looks like its the solar panel aspect that is not delivering the power with the seasons changing, and some loss of solar.  a) So anything you can do to help out a better solar aspect  – less shade would help, and  solar panels are best set at an optimal 120 from horizontal for that location (h…[Read more]

The non recharge batteries could work – but you need to do a lot more power calculations to understand how long they will work.  4 batteries (4*1.6V =6V) will work for a boost plugged in…[Read more]
