pigpio-dht 0.3.6

Code

# NOTE: The import has a _ not - in the module name.
from pigpio_dht import DHT11, DHT22

gpio = 21 # BCM Numbering

sensor = DHT11(gpio)
#sensor = DHT22(gpio)

result = sensor.read()
print(result)

Output

{'temp_c': 20, 'temp_f': 68.0, 'humidity': 35, 'valid': True}

from pigpio_dht import DHT11, DHT22

gpio = 21 # BCM Numbering

sensor = DHT11(gpio)
#sensor = DHT22(gpio)

result = sensor.sample(samples=5)
print(result)

Output

{'temp_c': 20, 'temp_f': 68.0, 'humidity': 35, 'valid': True}

Parameters

• retries number of times to keep retrying when the result contains valid = False

Returns

A Dictionary in the form {'temp_c': 20, 'temp_f': 68.0, 'humidity': 35, 'valid': True}

Where:

• temp_c is the temperature in degrees Celsius

• temp_f is the temperature in degrees Fahrenheit

• humidity is the relative humidity

• valid is true only if sensors checksum matches with returned data.

Discard readings where value == False and try again.

Raises

TimeoutError

• If the sensor on gpio does not respond

• If the sensor responds within timeout_secs (see _Constructor), but the response cannot be understood by the library. Try increasing timeout_secs

Raises

TimeoutError

• Same as for read(), plus

• If max_retries is reached
