Avery Dennison Magnus S2 and S3 Passive Sensor Technical Guide

The guide explains the design and functionality of Avery Dennison’s passive RFID sensor tags that employ a single‑chip solution (Axzon Magnus S2 or S3). It covers how the sensors adjust internal capacitance to compensate for antenna detuning caused by moisture, metal, or pressure, enabling battery‑free operation in sensitive environments.

It also details the UHF EPC Class 1 Gen 2 communication protocol, memory layout, and recommended software techniques for high‑accuracy data acquisition, including RSSI‑based power management and temperature calibration methods. This manual is written in Chinese.
