SparkFun Atmospheric Sensor Breakout - BME280 (with Headers)

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.

  • Operation Voltage: 3.3V
  • I2C & SPI Communications Interface
  • Temp Range: -40C to 85C
  • Humidity Range: 0 - 100% RH, =-3% from 20-80%
  • Pressure Range: 30,000Pa to 110,000Pa, relative accuracy of 12Pa, absolute accuracy of 100Pa
  • Altitude 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 Small
  • Pre-soldered Headers

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
