ROHM's new barometric pressure sensor, the BM1390GLV (-Z), is characterised by its compact size and extremely high accuracy; rated IPX8 for water resistance, it is ideal for home appliances, industrial equipment and compact IoT devices.
Barometric pressure sensors have become popular with wearable devices and smartphones for 'indoor navigation', as well as for altitude data in activity meters.
In recent years, as applications have increased, there has been a greater demand for smaller, water-resistant barometric pressure sensors that are robust and resistant to external interference.
In response to this question, ROHM has developed a new barometric pressure sensor, a product that is resistant to water and temperature fluctuations as well as mechanical stress.
The BM1390GLV combines MEMS technology and control circuitry designed in the past with original waterproof technology to provide IPX8-rated water resistance in a compact 2 × 2 × 1 mm package size.
In addition, a built-in proprietary temperature compensation function ensures superior thermal characteristics, while the ceramic package minimises variations in device-specific characteristics caused by mechanical stress during mounting on the board.
These features allow barometric pressure measurements of very high accuracy in applications requiring water resistance, a property difficult to achieve so far, and in environments exposed to major temperature variations.
