Aurasemi – IoT Sensors (AU2001) (10/2023)

The AU2001 is a position sensor IC targeted for water & gas metering applications. It covers a range of working distance required in water & gas meters. The IC supports SPI for simple interface with micro controllers. The IC works on a wide range of supply from 2.4 V-3.6 V. The IC supports two modes – low sensitivity mode for lesser sensing distance and high sensitivity mode for larger sensing distance. The average current is less than 0.6 uA in low sensitivity mode and less than 4.5 uA in high sensitivity mode, when triggered once in 125 ms. The IC is available in 3 mm x 3 mm 16 pin QFN package.
