The BME280 is a great new chip which was originally designed for the next generation of smartphones. With an I2C connection you have access to enough weather data to make some pretty good predictions for your local area. BME280, the precision sensor from , is soldered onto PCB. Not only the pressure and the temperature, this sensor can measure humidity. It uses both I2C and SPI (supports 3-, 4-wire SPI) interface Board Mount Humidity Sensors The BME280 is an integrated environmental sensor developed specifically for mobile applications where size and low power consumption are key design constraints.
Specifications:
Supply Voltage: 1.8 - 5V DC Interface: I2C (up to 3.4MHz), SPI (up to 10 MHz)
Applications - 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, ventilation, air conditioning (HVAC) - Internet of things - GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection) - Indoor navigation (change of floor detection, elevator detection) - Outdoor navigation, leisure and sports applications - Weather forecast - Vertical velocity indication (rise/sink speed)
