PSExampleApp
Read full descriptionHide full description
The PSExampleApp is a simple open-source application that guides a user to do a measurement with a PalmSens device to measure concentrations in a liquid sample. The app can be re-configured without code for use with (bio)sensors measuring a specific analyte using a linear calibration curve. The application provides clear instructions, so that the user follows a simple flow to connect to a device and run a measurement with just a few taps. The appโs default configuration is set for detection of Heavy Metals using ItalSens screen-printed-electrodes for heavy metal detection. It can be download from the app store and configured for your own need or serve as an example for your own app. The source code can be found at: https://github.com/PalmSens/PSExampleApp .
