I've been following this thread and have bought a variety of little panels to experiment with.
These 5.5v 4F 'supercaps' have arrived in the post and I'm not sure how I should test them.
For now I would just like to see how well they hold a charge. What's the best procedure to test them?
Hi,
Probably being over-optimistic as usual but...
Is it feasible to create a system with the following items:
Solar Garden Lights: Example
DC Booster ie http://www.ebay.es/itm/112468163238
or https://es.aliexpress.com/item/0-7-5V-to-3V-3-3V-5V-DC-DC-Boost-Converter-voltage-Step-up-Module/32800430445.html
ESP32 or ESP8266
Moisture Sensor
that at night takes a reading from a moisture sensor and sends it via wifi to a control.
I guess that the battery would have to be able to keep enough power for 24hr of sleep mode for the ESP and then for the sending of data once a day.
Later I plan to swap the battery for a supercapacitor and create some sort of irrigation system but for now I just want to know if the battery from a small solar light will work through a booster in this way?
Thanks,
