NXP Semiconductors NHS3152
The NHS3152 is an IC optimized for therapy adherence monitoring and logging. It has an embedded NFC interface, a resistive network sensing-interface, an internal temperature sensor, and a direct battery connection. These features support an effective system solution with a minimal number of external components and a single layer foil implementation for pill usage monitoring.FEATURES AND BENEFITS
