Humidity and pressure sensor developed specifically for mobile applications

04-03-2015 | Mouser Electronics | Test & Measurement

Bosch's BME280 humidity and pressure sensor is an integrated environmental
sensor developed specifically for mobile applications where size and low
power consumption are key design constraints.

Now in stock at Mouser, the unit combines individual high linearity, high
accuracy sensors for pressure, humidity and temperature in an 8-pin
metal-lid 2.5mm x 2.5mm x 0.93mm LGA package, designed for low current
consumption (3.6µA at 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 absolute barometric pressure sensor 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.
