AOSongDHT class

Base classes

class Sensor: The "Sensor" class is used for all sensor-level operations - waking, sleeping, and taking measurements.

AOSongDHT(int8_t powerPin, int8_t dataPin, const uint8_t type, uint8_t measurementsToAverage = 1): Construct a new AOSongDHT object - need the power pin, the data pin, and the sensor type.
~AOSongDHT(): Destroy the AOSongDHT object - no action needed.

bool setup(void ) override: Do any one-time preparations needed before the sensor will be able to take readings.
String getSensorName(void ) override: Get the name of the sensor.
bool addSingleMeasurementResult(void ) override: Get the results from a single measurement.

Construct a new AOSongDHT object - need the power pin, the data pin, and the sensor type.

Parameters
powerPin	The pin on the mcu controlling power to the AOSong DHT. Use -1 if it is continuously powered. The DHT requires a 3.3 - 6V power source
dataPin	The pin on the mcu receiving data from the AOSong DHT
type	The type of DHT. Possible values are DHT11, DHT21, AM2301, DHT22, or AM2302. NOTE: The DHT type should be entered without quotation marks since the values are members of an enum rather than a string.
measurementsToAverage	The number of measurements to take and average before giving a "final" result from the sensor; optional with a default value of 1.

Do any one-time preparations needed before the sensor will be able to take readings.

Returns	bool True if the setup was successful.

This sets the pin modes of the _powerPin and _dataPin, updates _sensorStatus, and returns true.

Get the name of the sensor.

Returns	String The sensor name as given in the constructor.

Get the results from a single measurement.

Returns	bool True if the function completed successfully.

This asks the sensor for a new result, verifies that it passes sanity range checks, and then adds the value to the result array.
