Logging and retrieving large bursts of sensor data from an Arduino
First up, determine how many bytes for how long. Would this fit in your available ram? With an Arduino Uno, you’ve not got much ram, so that choice of platform is probably not going to work for you. Something like an esp32-wrover has 4MB of external ram and is supported with the Arduino software obviously has a lot more wiggle-room ram wise. Depending on how much actual data you collect, there may be room on the module’s flash to store it more permanently or there’s the choice of external flash, sdcard or just dump it out WiFi.
