## Description

This application is used to communicate with EnvLoggers via NFC (near field communication). Users can configure missions, plot mission data and save them as CSV files to the phone&#39;s memory. It also offers the option to instantaneously share data.<br><br>Data are saved as CSV files, which are human-readable and easily imported into R, MatLab, Excel or similar.<br><br>EnvLoggers are contactless miniaturized temperature loggers. Their main features are:<br><br>1. They are sturdy, waterproof, and resistant to UV. Can withstand depths exceeding 500 meters.<br><br>2. Their battery life spans over 2 years (sampling at every hour).<br><br>3. The memory stores between 10k readings @ 0.1 ºC resolution or 12k readings @ 0.5 ºC resolution. Typically, 14k readings @ 0.1 ºC resolution and 17k @ 0.5 ºC resolution. For reference, 1 year of data at hourly resolution requires ~9K readings. Memory is non-volatile, meaning that data can be retrieved even after battery depletion.<br><br>4. The clock drift is of 50 ppm at most.<br><br>5. The temperature resolution is of 0.1 ºC. Precision and accuracy are of at least 0.2 ºC.<br><br>6. Because the NFC allows for communication at a range of a few cm, it is possible to embed the loggers in the rock and still communicate with them.<br><br>Refer to www.electricblue.eu for more information.
