Bosch Sensortec BME280 – Combined Humidity And Pressure Sensor

The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. The BME280 is register and performance compatible to the Bosch Sensortec BMP280 digital pressure sensor. The BME280 achieves high performance in all applications requiring humidity and pressure measurement. These emerging applications of home automation control, in-door navigation, E-Textiles, fitness as well as GPS refinement require a high accuracy and a low TCO at the same time. The humidity sensor provides an extremely fast response time for fast context awareness applications and high overall accuracy over a wide temperature range. The integrated temperature sensor has been optimized for lowest noise and highest resolution. Its output is used for temperature compensation of the pressure and humidity sensors and can also be used for estimation of the ambient temperature. The sensor provides both SPI and I²C interfaces.

Typical Application

• Context awareness, e.g. skin detection, room change detection
• Fitness monitoring / well-being
• Warning regarding dryness or high temperatures
• Measurement of volume and air flow
• Home automation control
• Control heating, venting, air conditioning (HVAC)
• Internet of Things
• GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
• Indoor navigation (e.g. change of floor detection, elevator detection)
• Outdoor navigation, leisure and sports applications
• Weather forecast
• Vertical velocity indication (rise/sink speed)
• E-Textiles and Wearable

Target Devices

• Handsets such as mobile phones, tablet PCs, GPS devices
• Navigation systems
• Gaming (e.g flying toys)
• Camera (DSC, video)
• Home weather stations
• Flying toys
• Watches
• E-Textiles
• Wearable
