### BME280
This is using `bme280` library; one sensor is allowed based on I2C
address on the bus, normally `0x10`, but configurable with `sensors.bme280_i2caddr`
in `mos.yml`. The chip is polled with a period of `sensors.bme280_period`
which defaults to 3 seconds, each sensor reading takes approximately 4ms.
Note that there are several versions of this popular barometer chip: BME280
is fully fledged and includes a hygrometer (measuring the relative humidity),
while BMP280 does not.
Please see the upstream [source](https://github.com/mongoose-os-libs/bme280)
for more information on the driver.
