GY-BME280 Temperature, Humidity and Barometric Pressure Sensor (5V)

Rather than wiring up a separate temperature sensor, a separate humidity sensor, and a separate pressure sensor, this breakout reads all three environmental measurements from one BME280 chip over a single I2C connection, which keeps a weather station or environment-logging project's wiring and code noticeably simpler. Its pressure readings are accurate enough to derive a usable altitude estimate just like a standalone barometric sensor, while the combined humidity and temperature data is exactly what a basic weather station, greenhouse monitor, or indoor air-quality logger needs. The onboard 5V regulation on this particular breakout makes it easy to power directly from common 5V microcontroller boards without needing a separate 3.3V supply rail.
