em | aura-sense (EM4152)- EPC and UHF ICs

RAIN RFID Sensor Transponder IC

General Description

em|aura-sense is a member of the latest generation family of EM Microelectronic RAIN RFIDTM devices. The chip combines capacitive sensing and RAIN RFID technology
used for long range application purposes.

Target applications and market segments include smart manufacturing and industry 4.0 applications, predictive maintenance, Internet of Things (IoT), industrial sensing, and
home automation.

The chip is compliant with ISO/IEC 18000-63 and EPCTM Gen2v2.

The em|aura-sense device allows to interface and capture sensing data with external sensor(s). Sensor commands are available to request sensing acquisition and store in the memory.

The capacitive sensor is external to the chip and can either be integrated in the inlay or as a separately mounted component, e.g. as an SMD component.
em|aura-sense offers a versatile non-volatile memory which is accessible via the RAIN RFID air interface and can be used for storing sensing information. Each IC is manufactured with a 96-bit unique Tag Identifier (TID) and delivered with a default 96-bit EPC encoded value that is a copy of the 96-bit TID.
