This is a library for the BME280 humidity, temperature & pressure sensor
|
|
This example shows how to take Sensor Events instead of direct readings
|
|
|
|
Designed specifically to work with the Adafruit BME280 Breakout
|
|
----> http://www.adafruit.com/products/2652
|
|
|
|
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
|
|
to interface.
|
|
|
