Bosch Sensortec - Model BMP585 -Barometric Pressure Sensor for Precise Altitude Measurement
The BMP585 is a high-precision barometric pressure sensor designed by Bosch Sensortec, offering robust performance for a wide range of applications, especially in fitness tracking wearables. With an exceptional accuracy capable of detecting height changes of a few centimeters, this sensor is indispensable for activities requiring precise altitude measurement, such as fitness training, navigation, and water level detection. It features a gel-filled cavity providing superior protection against water and chemical intrusion, making it suitable for use in harsh environments. The BMP585 has a maximum absolute accuracy of ±50 Pa and a temperature coefficient offset of ±0.5 Pa/K. Thanks to its compact design, the sensor provides flexibility, facilitating easy integration into various devices, including smartwatches, hearables, and industrial products. Particularly advantageous for applications requiring reliability in extreme conditions, the BMP585 is a versatile component for both consumer electronics and industrial instrumentation.
Carefree ready for any adventure. Barometric pressure sensors are a key component in fitness tracking wearables and other applications, enabling altitude to be accurately determined. With its extreme accuracy, BMP585 measures a change in height of just a few centimeters. It can therefore detect movements in fitness training down to the level of individual pull-ups or push-ups. At the same time, users do not have to worry about environmental conditions - thanks to its extreme ruggedness.
The BMP585 has a gel-filled cavity that allows highest protection against water and other liquids such as chemicals with the suitable integration concept. The sensor can be used for applications like height measurement, water-level detection and navigation with a maximum absolute accuracy of ±50 Pa and an temperature coefficient offset (TCO) of ±0.5 Pa/K.
The new BMP585 sensor with its small footprint offers outstanding design flexibility, providing a single package solution that is easy to integrate into other existing and upcoming devices for smartwatches, other wearables, hearables, home appliances, smart homes, and industrial products.
