    BME280

    The BME280 is an integrated environmental sensor developed specifically for mobile applications where size and low power consumption are key design constraints. The unit combines individual high linearity, high accuracy sensors for pressure, humidity and temperature in an 8-pin metal-lid 2.5 x 2.5 x 0.93 mm³ LGA package, designed for low current consumption (3.6 μA @1Hz), long term stability and high EMC robustness.

    The humidity sensor features an extremely fast response time which supports performance requirements for emerging applications such as context awareness, and high accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor with features exceptionally high accuracy and resolution at very low noise. The integrated temperature sensor has been optimized for very low noise and high resolution. It is primarily used for temperature compensation of the pressure and humidity sensors, and can also be used for estimating ambient temperature.

    The BME280 supports a full suite of operating modes which provides the flexibility to optimize the device for power consumption, resolution and filter performance."

    Wearables

    A wristband personal alarm clock will make sure that not only will you get up on time but also in sync with your natural biorhythm. A smartwatch can improve your health by detecting poor air quality in your environment. Smart fitness wear can improve the efficiency of your workout by measuring your speed and calorie consumption. What do all these wearable applications have in common? They are made possible by the almost invisible MEMS sensors and clever sensor solutions.
