API Reference – MyDHT22

⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻

## Constructor

## MyDHT22(uint8_t pin)

Initializes the DHT22 sensor on the specified digital pin.
	•	Parameters:
	•	pin – Arduino digital pin connected to the DHT22 data pin.
	•	Example:

MyDHT22 dht(7); // Uses digital pin 7

⸻

## readData()

bool readData()

Reads new data from the DHT22 sensor.
	•	Returns: true if reading is successful and checksum is valid, false otherwise.
	•	Must be called before accessing temperature or humidity.

if (dht.readData()) {
  // safe to call getTemperature() and getHumidity()
}

⸻

## getTemperature()

float getTemperature()

Returns the last temperature reading in degrees Celsius.
	•	Return Type: float
	•	Note: Call only after readData() returns true.

float temp = dht.getTemperature();

⸻

## getHumidity()

float getHumidity()

Returns the last humidity reading in percentage (%RH).
	•	Return Type: float
	•	Note: Call only after readData() returns true.

float hum = dht.getHumidity();

⸻

Notes
	•	Timing-sensitive: Uses delayMicroseconds() for signal timing.
	•	Non-blocking read not supported.
	•	Avoid using with other time-critical tasks.
	•	Compatible with AVR-based boards (e.g. Arduino Uno, Nano).
