Hello!
I apologize in advance if this question has already been answered. I’ve found it difficult to find a solution despite my searches.
I recently received a Micro:Climate Kit and was hoping the entire setup would run off the included 3v AAA battery pack – including the OpenLog data logger. I have followed the experiment guides and all seems to run perfectly fine when powering the kit over the micro USB connection (off a 5v wall charger) with a very long cable out to the weather station. I have set the OpenLog data logger up to record data frequently (every five seconds or so) so that I could check the LEDs are running.
When I switch to the included 3v power supply included in the Micro:Climate Kit the system no longer collects data through the OpenLog. I seem to be able to run the micro:bit’s LED screen of the 3v battery pack but again, my use case really depends on checking the data every few days using the included logger.
I’ve attempted to run the entire thing off a few different battery power brick (phone chargers) but the setup draws so little power it only lasts about 5-10 seconds before those packs shut off.
I was thinking perhaps the microSD card I was using (small 4GB card) was causing the trouble, but now I’ve used a variety of FAT32 formatted microSD cards including a brand new Lexar 32GB class 10 card and a Kingston 64GB with no luck. Depending on how the product page description is read the OpenLog supports up to 32GB (or is it 64GB??). Alas, I am relatively convinced the microSD cards I’m using are not the issue here.
Hoping someone has run into this problem before. Happy to provide more information, but wanted to start here. Thanks to any and all who offer their expertise and assistance.
