This application is designed to check your Android device with attached 1-wire-products from Maxim Integrated (Dallas Semiconductor):
USB-to-1-Wire-Adapter DS9490R
1-Wire Digital Thermometer DS18B20 or DS18S20 (=DS1820)


The Android device must be able to run in USB-Host-Mode. Be aware that not all devices sold with Host-Mode really support all necessary functionality.

If you do not have these devices, this app is useless to you.

Attach the USB-to-1-Wire-Adapter to your device and the temperature sensor to your adapter. "parasite power modus" (2 wires) and "external power modus" (3 wires) are possible. Then start the app. If anything is working properly you will see the unique IDs of the Adapter and Sensor. The current temperature reading will be displayed for a short time.
