Types ¶
type AHT20 ¶
type AHT20 struct {
// contains filtered or unexported fields
}
AHT20 wraps an I2C connection(github.com/d2r2/go-i2c) to an AHT20 .
func AHT20New ¶
New creates a new AHT20 connection. The I2C bus must already be configured.
This function only creates the AHT20 object, it does not touch the AHT20.
func (*AHT20) RawHumidity ¶
func (*AHT20) Read ¶
Read the temperature and humidity
The actual temperature and humidity are stored and can be accessed using `Temp` and `Humidity`.
func (*AHT20) ReadWithRetry ¶
func (*AHT20) RelHumidity ¶
