NPA 201 Digital Output Absolute Pressure Sensor from NovaSensor for Wearable and Portable Applications

NovaSensor NPA 201

NovaSensor, a division of Amphenol Advanced Sensor Group, announces the release of their newest product, the NPA-201 barometer/altimeter. The NPA-201 at its heart is a customized version of the popular NPA series in that it has a custom pressure range of 260 to 1260 mBar, with a temperature compensated, digital (I²C) output in a small industry standard 8 pin HCLGA package. This device can be powered with a 1.7 to 3.6V power supply, and sleep rate current is <250nA, making it ideal for wearable and portable applications.

Like Most HCLGA packages, this device can be hard to prototype as the blind solder pads are difficult to solder, so NovaSensor has also released the NPA-201 breakout board. The breakout board allows users to quickly evaluate the NPA-201 sensor for their application, before needing to have a small amount of custom bread boards made. The NPA-201 breakout board will allow your project to go to market quicker.
