Detailed Description

Class that stores state and functions for interacting with the AHT10/AHT20 I2C Temperature/Humidity sensor.

Member Function Documentation

◆ begin()

bool Adafruit_AHTX0::begin	(	TwoWire *	wire = `&Wire`,
		int32_t	sensor_id = `0`,
		uint8_t	i2c_address = `AHTX0_I2CADDR_DEFAULT`
	)

Sets up the hardware and initializes I2C.

Parameters

wire	The Wire object to be used for I2C connections.
sensor_id	The unique ID to differentiate the sensors from others
i2c_address	The I2C address used to communicate with the sensor

Returns: True if initialization was successful, otherwise false.

◆ getEvent()

bool Adafruit_AHTX0::getEvent	(	sensors_event_t *	humidity,
		sensors_event_t *	temp
	)

Gets the humidity sensor and temperature values as sensor events.

Parameters

humidity	Sensor event object that will be populated with humidity data
temp	Sensor event object that will be populated with temp data

Returns: true if the event data was read successfully

◆ getStatus()

uint8_t Adafruit_AHTX0::getStatus ( void )

Gets the status (first byte) from AHT10/AHT20.

Returns: 8 bits of status data, or 0xFF if failed

◆ getTemperatureSensor()

Adafruit_Sensor * Adafruit_AHTX0::getTemperatureSensor ( void )

Gets the Adafruit_Sensor object for the AHTx0's humidity sensor.

Returns: Adafruit_Sensor*

◆ getHumiditySensor()

Adafruit_Sensor * Adafruit_AHTX0::getHumiditySensor ( void )

Gets the Adafruit_Sensor object for the AHTx0's humidity sensor.

Returns: Adafruit_Sensor*
