Application Note

SPSPRDR1-8 Remote Update Guide

ON Semiconductor Battery Free Wireless Sensor tags powered by a Magnus−S integrated circuit (IC) family of sensing RFID chips are fully compliant with the EPC Generation−2 UHF RFID but can most effectively utilize existing reader hardware after the firmware and API have been optimized for sensing. This note guides through the process of updating the reader with the latest firmware adding additional support and functionalities.

Application Note

Data Center Environmental Monitoring Using Smart Passive Sensors

Sensor applications in a data center fall into two main categories: sensors inside the rack and sensors outside the rack. This application note covers both inside and outside the rack sensors, as well as providing further detail on temperature sensors for data centers.

Application Note

Battery Free Wireless Sensor Measurements

ON Semiconductor’s Battery Free Wireless Sensor tags powered by a Magnus−S integrated circuit (IC) produce a Sensor Code which gives information about the sensor tag’s environment. To maximize the precision of sensor measurements, the user should understand and account for effects related to the reader transmission frequency and the amount of power received by the sensor tag. This note describes those effects and discusses strategies for addressing them.

Application Note

Moisture Intrusion Detection System: “Solving Water Leak Inspection Challenges on Vehicle Assembly Lines”

“Water Leaks” have plagued the auto industry for years. About 3% of new vehicles leave the factory with leaks large enough to cause mold growth and damage to expensive electronic components. Catching leaks at the factory requires a new approach to leak detection. Since getting to the leak areas is challenging, what’s needed are water sensors located in these locations, under the carpet and in the thin spaces between plastic panels and door moldings.
