BME280 대기압 센서
(SparkFun Atmospheric Sensor Breakout
- BME280 (with Headers))
개요
- 본 제품은 BME280을 탑재한 대기압센서입니다.
- 대기압/습도/온도를 쉽게 측정할 수 있어 대기 상태나 조건에 관한 필요한 정보를 본 센서 하나로 얻을 수 있습니다.
- BME280 칩 자체는 실내나 실외, 날씨 예보, 홈 오토메이션, 개인 건강 환경 모니터링 등에 사용할 수 있게 디자인 되었습니다.
- 30kPa-11kPa까지의 대기압을 측정 가능합니다.
- 3.3V SPI 인터페이스, 5V tolerant I2C 인터페이스(with pull-up resistors to 3.3V)를 제공하며, 센서 측정시 1mA, 아이들이 5uA 이하로 전류를 소비합니다.
- 보드에는 10핀이 나와 있지만 6개이상이 한번에 사용될 일은 없습니다.
- 보드 좌측은 전원, 그라운드, I2C 핀이며, 나머지 핀은 SPI 기능을 제공합니다

The SparkFun BME280 Atmospheric Sensor Breakout with Headers 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 designed 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 SPI interface, a 5V tolerant I2C interface (with pull-up resistors to 3.3V), takes measurements at less than 1mA and idles less than 5µA. The BME280 Breakout board has 10 pins, but no more than six are used at a single time. The left side of the board provide power, ground, and I2C pins. The remaining pins which provides SPI functionality and have another power and ground, are broken out on the other side.
Note: This version of the BME280 comes with headers already soldered on. If you are looking for the BME280 Atmospheric Sensor Breakout without headers, it can be found here or in the Similar Products below.
