bme680_readSensor()

char bme680_readSensor

(

bme680_t *

dev

)

Instructs the BME680 sensor to take a reading.
Readings take approximately 200ms and should be retireved using bme680_temperature(), bme680_pressure(), bme680_humidity(), bme680_altitude(), and bme680_gasResistance().

Note

The internal heating element for the gas (VOC) sensor can skew temperature and humidity readings if the sensor is read at intervals of under 3 seconds. If frequent temperature and humidity readings are desired, use bme680_heaterDisable() to prevent the heating element from turning on.

Parameters

*dev	pointer to the bme680 device.
