The cuplTag is an NFC datalogger. It periodically wakes up, collects 12-bit temperature and humidity readings and writes these into a circular buffer on an NFC EEPROM. The buffer forms part of a URL query string. When cuplTag is tapped by an NFC-capable phone, its URL automatically opens in a browser. A web application (cupldeploy) decodes sensor readings and displays them in a graph. Users can view sensor readings in one tap, without installing an app on their phones first.
