USB-Dataloggerreader for Android
(c) 2011-2020 by Markus Hoffmann
This app allows to use external USB data loggers together with your tablet computer or smart-phone. It implements an interface to temperature, humidity, pressure, sound, voltage, current and or CO-gas concentrations USB data loggers. (It is supposed to run only on tablet computers and smart-phones, which have a USB-(Host)-connection/plug. Android versions >3.1)
It implements following functions:
- Configuration of the logger,
- readout of the configuration,
- Start and Stop of the logging,
- Readout of the measurement data,
- Preview the data in a plot,
- save the data into a file (.csv or ASCII).
- examine the data in an interactive plot.
Following data logger devices are supported:
- Voltcraft DL-120-TH, DL-100-T
- Voltcraft DL-121-TH, DL-101-T, DL-181-THP
- Voltcraft DL-141-TH (experimental)
- Voltcraft DL-200T, DL-210TH, DL-220THP, DL-230L, DL-240K (new)
- CEM DT-171 (not tested)
- Lascar EL-USB-1,2,3,4
- Lascar EL-USB-LITE,CO,TC,CO300,2-LCD,2+,1-PRO,TC-LCD,2-LCD+ (not tested)
- Lascar EL-USB-5,1-RCG,1-LCD,OEM-3 (not tested)

- FreeTec NC7004-675 white, ecowitt DS102 (new)

There are currently issues with Android 10. Android 10 is not backwards compatible. So some loggers are not detected anymore on Android 10. So better avoid upgrading until we have a fix.

Building the .apk file
The build uses the gradle environment. A ./gradlew build should do.
git clone email@example.com:kollo/USBDataloggerreader-Android.git
then do a cd USBDataloggerreader-Android ./gradlew build (Enter passwords for the keystore) (the compile process will take a while.)
The apk should finally be in build/outputs/apk/USBDataloggerreader-Android-release.apk
