Whether you're building a weather station, home automation system, or indoor air quality monitor, this sensor covers all the key atmospheric conditions.\n\nThe breakout provides both a 3.3 V SPI interface and a 5 V tolerant I²C interface (with pull-up resistors to 3.3 V). It draws less than 1 mA during measurements and idles at less than 5 µA, making it well suited for battery-powered projects.\n\nKey Features\n\n\nThree-in-One Sensor – Pressure, humidity, and temperature from a single IC\n\nPressure Range – 30 kPa to 110 kPa (relative accuracy ±12 Pa, absolute ±100 Pa)\n\nHumidity Range – 0–100% RH (±3% accuracy between 20–80% RH)\n\nTemperature Range – −40 °C to +85 °C\n\nAltitude Accuracy – ±1 m relative at sea level\n\nDual Interface – I²C (5 V tolerant) and SPI (3.3 V)\n\nUltra-Low Power – Less than 1 mA active, less than 5 µA idle\n\n\nIdeal For\n\nWeather stations and environmental monitoring\nIndoor/outdoor navigation and altitude sensing\nHome automation and HVAC systems\nPersonal health and wellness tracking\n\n\nPackage Contents\n\n1× SparkFun BME280 Atmospheric Sensor Breakout\n\n\n\nNote: Headers are not included and will need to be purchased and soldered separately.\n\n\nResources\n\nBME280 Datasheet (PDF)\nHookup Guide\nArduino Library (GitHub)\nSchematic (PDF)\nDesign Files (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":11540,"title":"Default Title","sku":"SF-SEN-13676","price":50.71,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
