The BME280 is intended for use in smartphones and wearable devices where it can provide support for home automation control and sport and fitness use cases. The pressure element can be used to provide floor-level tracking for indoor navigation.

The humidity sensor within the BME280 measures relative humidity from 0 to 100 percent across a temperature range from -40°C to +85°C with a response time of less than 1 second. The humidity measurement accuracy is ±3 percent with a hysteresis of 2 percent or better, and the temperature reading accuracy is within 0.5°C. The current consumption of only 3.6 µA (at 1 Hz) makes the BME280 Integrated Environmental Unit particularly suitable for battery-driven applications. The relative accuracy of pressure readings is ±0.12 hPA, which equates to ±1 meter of altitude difference at a resolution of 1.5cm.

The device comes with I2C and SPI serial digital outputs and packaging measures 2.5mm by 2.5mm with a height of 0.93mm in an 8-pin LGA package.

Bosch Sensortec also provides support software. The BSH1.0 algorithm enables developers to implement a temperature compensation function.

The BME280 samples for development customers are available now.
