 Hello, I'm Gianmarco Ferrari I'm responsible for NFC solution for the region America. We are here at CS 2023 And we're going to present you the ST Evala SmartTag 2 sensor node the platform So ST Evala SmartTag 2 is an NFC enabled Ultralow power sensor node capable to sense temperature pressure light and motion and also Transfer the data when is triggered by a smartphone NFC enabled The connectivity of the platform is given by the ST25DV is an NFC dynamic tag It's a passive device with a wireless interface NFC compliant To transmit the data to the smartphone and a wired interface and a square C bus to communicate with the microcontroller To retrieve the data from the sensor The microcontroller we use is an STM32 ultralow power Cortex-M4 plus We have sensors environmental sensor. We have an high accuracy pressure sensor digital barometer with 0.5 hectopascal accuracy We have a digital temperature sensor with high accuracy of 0.5 degree Celsius Ambient light is lax and CCT color sensor with True flicker extraction engine In terms of inertial sensor, we have an ultralow power accelerometer 16g accelerometer full scale with a finite state machine and machine learning core with QVAR sensing channel and anti-lizing filter We have the IG accelerometer is 100 200 and 400 g Dynamically selectable full scales and also an IMU is an ultralow power IMU We've also finished the state machine and machine learning core To to enable reliable motion tracking and Contextual awareness as optional Anesthe safe secure element that can be implemented to it's a certified security solution from the node to the infrastructure also optional We have preset NFC wireless charging to be able to charge the the battery of the node The sensor node that can work a battery power To be able to do Data logging of all the sensor data into the dynamic tag or it can work also battery less But the rest of functionality is provided by the NFC dynamic tag Energy harvesting capability. So when the phone is applied is is Connecting to the NFC dynamic tag provides Energy this energy that is not used by the tag is available on a V out pin And it's able to power all the all the node and retrieve the data without without power It's the avala smart tag to Platform comes up with a form factor hardware its own firmware a dedicated app for both Android and in iOS and also a cloud dashboard to be able to project Distance to monitor the node with is a telemetry geolocation and also time stamp Estee avala start up to can be used as a solution for a set tracking for Predicting maintenance or for battery less sensing the benefit of the smart tag To platform is basically is a low cost very low power easy to implement and to certified as a solution and Thank you very much for listening to this presentation if you would like more information You can find the at the city comm slash st25 all the information and the platform is also available For purchase at the city comm or your local distributor. Thank you very much
