Atmospheric Sensor Breakout — BME280 3.3V

The BME280 Atmos­pher­ic Sen­sor Break­out is the easy way to mea­sure baro­met­ric pres­sure, humid­i­ty, and tem­per­a­ture read­ings all with­out tak­ing up too much space. Basi­cal­ly, any­thing you need to know about atmos­pher­ic con­di­tions you can find out from this tiny break­out. The BME280 Break­out has been design to be used in indoor/outdoor nav­i­ga­tion, weath­er fore­cast­ing, home automa­tion, and even per­son­al health and well­ness mon­i­tor­ing.The on-board BME280 sen­sor mea­sures atmos­pher­ic pres­sure from 30kPa to 110kPa as well as rel­a­tive humid­i­ty and tem­per­a­ture. The break­out pro­vides a 3.3V tol­er­ant I2C inter­face , takes mea­sure­ments at less than 1mA and idles less than 5µA. The BME280 Break­out board has 4 pins, The side of the board pro­vide pow­er, ground, and I2C pins.FEATURESOper­a­tion Volt­age: 3.3VI2C Com­mu­ni­ca­tions Inter­faceTemp Range: ‑40C to 85CHumid­i­ty Range: 0 — 100% RH, =-3% from 20–80%Pres­sure Range: 30,000Pa to 110,000Pa, rel­a­tive accu­ra­cy of 12Pa, absolute accu­ra­cy of 100PaAlti­tude Range: 0 to 30,000 ft (9.2 km), rel­a­tive accu­ra­cy of 3.3 ft (1 m) at sea lev­el, 6.6 (2 m) at 30,000 ft.Incred­i­bly SmallDOCUMENTSLibrary & Exam­ple Code
