Other supported demonstration boards will become available. - Use the APP to configure the firmware - Use the background reading or a generic NFC reading APP such as NXP's Tag Info to read out the dynamically created URL and launch it in your webbrowser. The NTAG SmartSensor range of ICs extends NXP's NFC portfolio of passive NFC tags and smart electronic devices. NTAG SmartSensor devices are single-chip solutions combining the now ubiquitous NFC smartphone connectivity with autonomous sensing, data processing and validation, and logging. The NTAG SmartSensor is easy to use in an application by simply adding an NFC antenna and a battery. The devices are also versatile and can be easily combined with other companion chips like radios or sensor solutions. This APP interacts with the NXP's NHS3100 IC, optimized for temperature monitoring and logging. The temperature sensor offers an absolute accuracy of 0.3C. Each chip comes pre-calibrated and NXP provides a certificate with NIST traceability, easing the use of this IC for medical and pharmaceutical applications. NXP delivers for the NHS3100 a starter kit which is available for both macOS and Windows.
