platypush.plugins.gpio.sensor.dht

class platypush.plugins.gpio.sensor.dht.GpioSensorDhtPlugin(sensor_type: str, pin: int, retries: int = 5, retry_seconds: int = 2, **kwargs)

Plugin to interact with a DHT11/DHT22/AM2302 temperature/humidity sensor through GPIO.

Requires:

• Adafruit_Python_DHT (pip install git+https://github.com/adafruit/Adafruit_Python_DHT.git)

__init__(sensor_type: str, pin: int, retries: int = 5, retry_seconds: int = 2, **kwargs)

Parameters

• sensor_type – Type of sensor to be used (supported types: DHT11, DHT22, AM2302).

• pin – GPIO PIN where the sensor is connected.

• retries – Number of retries in case of failed read (default: 5).

• retry_seconds – Number of seconds to wait between retries (default: 2).

get_measurement() → Dict[str, float]

Get data from the sensor.

Returns

A mapping with the measured temperature and humidity. Example:

{
    "humidity": 30.0,
    "temperature": 25.5
}

read(sensor_type: Optional[str] = None, pin: Optional[int] = None, retries: Optional[int] = None, retry_seconds: Optional[int] = None, **kwargs) → Dict[str, float]

Read data from the sensor.

Parameters

• sensor_type – Default sensor_type override.

• pin – Default pin override.

• retries – Default retries override.

• retry_seconds – Default retry_seconds override.

Returns

A mapping with the measured temperature and humidity. Example:

{
    "humidity": 30.0,
    "temperature": 25.5
}
