Hi,
I have temperature sensor data to save - 24 records per day.
The data history needs to be available for a month which gives me 744 int's.
Obviously with such a long period, the power may disappear, you would need to save this data somewhere to non-volatile memory. Which is better to use? The ESP doesn't have its own EEPROM only an emulated one, and this is too small anyway.
1. external EEPROM, e.g. 32k?
2. memory card?
3. something else?
