please recommend me a temperature logger.
- Log temperature in every minute OR log hourly minimum,maximum in every hour
- Centigrades preferred to e.g. Fahrenheit
- It requires intervention only monthly or even less frequently, so for instance:
- Can operate without a computer or external power source attached for at least a month (and can tell if it's due to replace/charge the battery in the next month, removable battery would be preferred)
- Has sufficient storage (or SD card capability) for at least one month worth of data
- Supported by linux, preferably ubuntu
- CSV time,temperature output would be preferred to any other more complex output file formats
- USB communication is preferred to bluetooth. Bluetooth is preferred to RS232
Thank you for your help in advance.
