The device memory is divided into 3 parts:
1. First part for regular data (collected following the intervals you set). For example, if you set to collect GPS and ENV every hour, ENV data at 1 hour, and ODBA data every 10 minutes, then 460 days of such data can be stored. If you reduce the intervals by half, then the duration also reduced by half.
2. Second part for BOOST data. When the solar charging condition is good, the device will automatically increase the data collecting frequency, such as 5 min GPS, or even 20s GPS. The data recorded this way will be stored separately, and a total of 99 days of such data can be stored.
3. Third part for x/y/z acceleration data. About 1.11 million pieces of such data can be stored, which equals to about 12 hours for continuous x/y/z acceleration data collecting at 25Hz.
If you require other plan, please specify.
