Bosch Sensortec is the market leader in barometric pressure sensors with more than 1 billion shipped products. The BMP380 is a very small, low-power and low-noise 24 bit absolute barometric pressure sensor. BMP380 is specifically designed and ideally suited for a wide range of altitude tracking applications. The new BMP380 offers outstanding design flexibility, providing a single package solution that can be easily integrated into a multitude of existing and upcoming devices such as smartphones, GPS modules, wearables and drones.
The sensor is more accurate than its predecessors, covering a wide measurement range from 300 hPa to 1250 hPa. This new barometric pressure sensor exhibits an attractive price-performance ratio coupled with low power consumption. It is available in a compact 10-pin 2.0 x 2.0 x 0.75 mm³ LGA package with metal lid.
- Altitude stabilization in drones
- Improved calorie expenditure measurement accuracy in wearables and mobile devices
- Unprecedented precision for outdoor/indoor navigation and localization applications
- Enhanced GPS accuracy outdoors
Look up! Have you noticed the increasing numbers of drones buzzing up in the sky these days? Most of these devices are toy quadcopters with low or no intelligence. However, there is a clear trend towards additional functionality that increases the controllability and by that the fun factor of such drones. Examples are an auto level mode for maintaining the drone's horizontal orientation, a constant altitude mode, or an orbit mode for circling around a specific point.
BMP280 is a barometric pressure sensor especially designed for mobile applications. The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow the implementation in battery powered devices such as mobile phones, GPS modules or watches.
The BME280 is an integrated environmental sensor developed specifically for mobile applications. The unit combines sensors for pressure, humidity and temperature in an metal-lid 2.5 x 2.5 x 0.93 mm³ LGA package.
