RAMSES - RFID Augmented Module for Smart Environmental Sensing

RAMSES is a fully-passive UHF RFID Tag with sensing and computing capabilities.

RAMSES relies on a new-generation RFID chip with a dual interface: a wired I²C interface managed by an ultra-low-power TI MSP430 MCU and a wireless UHF RFID Class-1 Generation-2 interface for communication with the reader.

RAMSES is self-powered by an RF energy-harvesting circuit enhanced by a DC-DC charge pump in Silicon-on-Insulator (SOI) technology but it is equipped also with a CR2032 lithium battery for Battery-Assisted-Passive (BAP) operations.

RAMSES is able to perform sensing and computing tasks. The communication with the interrogating reader uses the zero-power backscattering modulation.

Indoor performance:

10 meters of communication range in fully-passive mode

20 meters of communication range in BAP mode

Available sensors

- Digital TEMPERATURE sensor

- Digital AMBIENT LIGHT sensor

- Digital PRESSURE sensor         

- Digital 3-axis accelerometer
