ON Semi: rapid installation of battery-free smart passive sensors for IoT applications

ON Semiconductor has announced a complete wireless battery free sensing solution kit (SPSDEVK1) that allows the company’s innovative Smart Passive Sensors to be rapidly integrated into Internet-of-Things applications. The SPSDEVK1 solution kit is plug and play ready for users to immediately measure, aggregate and analyze the data for various IoT applications.

SPS wireless and battery-free sensors enable the monitoring of various parameters such as temperature, pressure, moisture or proximity at the network edge where running wires or replacing batteries may be impractical. When interrogated by an RF reader (the ON Semiconductor TagReader), the SPS “harvests” energy from the measuring signal, and then delivers a rapid and highly accurate reading from the sensor. This cost-effective solution has significant benefits over other technologies, and offers the potential to revolutionise low-power IoT sensing designs.

The newly announced SPSDEVK1 is a complete sensing solution that includes a UHF SPS reader hub (SPSDEVR1-8), eight UHF antennas (SPS1DEVA1-W), 50 temperature sensors (SPS1T001PCB), a 12 V DC power supply, and an Ethernet cable. Also included is ON Semiconductor’s TagReader software, an application specifically developed for reading SPS that enables the full functionality of the tags, giving a comprehensive system solution.

The TagReader software automatically detects the type of tag that is connected and reads sensor data graphically over time. A Graphical User Interface allows all system parameters related to the measurement process to be configured and re-configured as needed. As a result, with the SPSDEVK1, even first-time users can quickly and easily configure a system to measure, aggregate and analyse data for multiple fully wireless, battery-free IoT applications.
