Low power asset tag excels with five year battery life, says onsemi

Battery life has been a major obstacle to asset tag adoption, particularly within industrial sectors where reducing maintenance efforts and associated costs are a primary concern, acknowledged onsemi, introducing the RSL10 asset tag, which is claimed to overcome this challenge.

The asset tag is claimed to offer an industry-leading battery life of up to five years, compared to one year or less.

Contributing to this performance are an RSL10 Bluetooth 5 radio SoC and firmware enhancements. There is also a three-axis accelerometer and environmental sensors (motion, pressure and temperature) to provide data and insights on an asset’s environment, condition and orientation. Each sensor is powered by a dedicated MOSFET load switch, controlled by the RSL10. This design enables system power consumption to be controlled on a per-sensor basis, which decreases the total power used.

An inexpensive antenna, matching circuit optimised for Bluetooth Low Energy transmissions, a multi-purpose dome switch and a 10-pin debugger can be removed depending on the needs of the application.

The RSL10 can be used in indoor localisation beacons to track and monitor hospital equipment. The tags can be IP67-rated to meet the stringent sterilisation requirements of healthcare environments.

The RSL10 asset aag is available with a suite of development tools that include multi-protocol wireless support for Bluetooth Low Energy connectivity and the Quuppa Intelligent Locating System real time localisation services (RTLS) Intelligent Locating System RTLS (real time localisation services). Within the CMSIS-Pack, included with the evaluation board, onsemi has developed a custom application that demonstrates the low power features and capabilities of the platform in an asset tracking use-case.

The RSL10 asset tag is available now.

onsemi addresses vehicle electrification and safety, sustainable energy grids, industrial automation, and 5G and cloud infrastructure with a portfolio to create intelligent power and sensing technologies.
