Silicon

All of Axzon’s sensor solutions are powered by our innovative, ultra-low power sensing technology that allows sensing various physical quantities with the extremely low power harvested from an RFID reader signal.

Another unprecedented breakthrough is the sensitivity of our silicon sensor, which allows reliable sensing and communication with a compatible reader at distances up to 17 meters away.

The self-tuning Chameleon™ front-end on all or our allows our sensors to be placed on a variety of surfaces, without adverse impact to the chip’s sensitivity.

All these features make passive (or battery-free) sensing possible for applications ranging from automotive, industrial, supply-chain logistics and healthcare.


Magnus-3

The first in the family of our smart passive sensing silicon is Magnus, which is used for passively sensing temperature and moisture in a variety of industrial and healthcare applications. Both on-metal and off-metal tags have been designed using Magnus-3 to the suit the needs of the application.

RFM3300-D Magnus®-S3 M3D Passive Sensor IC

The RFM3300-D Magnus®-S3 M3D Passive Sensor IC extends the Magnus® line of Smart Passive Sensing™ ICs (Integrated Circuits). The Magnus-S3 M3D IC incorporates three sensors:

  1. The Chameleon engine generates a SENSOR CODE that quantifies the adaptive RF impedance setting used to match the sensor antenna. This is particularly useful for monitoring moisture levels.
  2. An on-chip Received Signal Strength Indicator RSSI monitor indicates the amount of RF power reaching the chip. It also allows the wireless reader to manage its output power for optimum sensor performance.
  3. The on-chip temperature sensor generates a TEMPERATURE CODE data value proportional to the temperature.

 

RFM3300-E Magnus®-S3 M3E Passive Sensor IC

The Magnus®-S3 M3E Sensor IC (Integrated Circuit) employs Smart Passive Sensing™ technology to enable a new class of maintenance-free and battery-free sensors. The Magnus-S3 M3E can be configured for low-cost sensors that monitor temperature, moisture, and proximity. The Magnus-S3 M3E IC incorporates two sensors:

  1. An on-chip Received Signal Strength Indicator RSSI monitor indicates the amount of RF power reaching the chip.
  2. The on-chip temperature sensor generates a TEMPERATURE CODE data value proportional to the temperature. The IC can be calibrated to provide precise temperature measurements.


Xerxes-I

Xerxes-I extends Axzon’s smart passive sensing capability by providing two analog ports to attach external low-power transducers, such as strain gauge bridges, pH electrodes or thermocouple assemblies, to name a few. The usual sensing functions built into the chip (temperature, moisture, RSSI), and the passive mode of operation, remain unchanged from its predecessor, Magnus. Xerxes-I provides a standard SPI interface to connect to a low-power microcontroller to enable truly smart sensor nodes that can process and log the sensed information, as well as provide alarm indications when necessary.

Xerxes-II

Xerxes-II adds data-logging capability to Xerxes-I, by incorporating flash memory on the chip and providing a means to externally power the chip from a battery or regulated power supply output from a microcontroller (MCU). A standard SPI port enables interfacing with an MCU for further processing and/or alarm indication by driving an LED or a display.
