Particle Photon / Core Library for BME280 sensors

Adafruit BME280 Particle Library

This is a library for the Adafruit BME280 Humidity, Barometric Pressure + Temp sensor

Particle Photon, Core & Electorn DHT Library based on Arduino Library for BME280 sensors adapted by Markus Haack

Works with the following BME280-Breakouts as well:

• http://www.watterott.com/en/BME280-Breakout-humidity-pressure-temperature-sensor
• http://www.adafruit.com/products/2652

These sensors use I2C or SPI to communicate, up to 4 pins are required to interface.

This library allows the user to:

• Read pressure in Pa
• Read temperature in °C and °F
• Read humidity in %RH
• Read altitude in meters
• Read altitude in feet

Hint: the default I2C address used by the library is (0x77), as in Adafruit_BME280.h. If you sensor board uses a different address you can set your own via the .begin(...) method.

Repository Contents
