Just to get a raw idea, can this accumulate enough power to gather a gps position and send it over wifi / 4g nb-iot signal ? I have only very basic knowledge so not enough to make an estimation of the kind of things this can power
While possible it is unlikely. It would take a considerable amount of time to accumulate that amount of energy needed from these sources. These systems are generally used for transmitters that transmit for a couple of seconds at most and may be off for the rest of the day. Enough energy would have to be accumulated to run the GPS long enough to get a valid fix etc.
Thanks so the ballpark estimation of how "intensive" it can be is 1 or 2 measure a day from a local sensor and transmission over 4g ?
