Pure Python library for reading DHT11 sensor on Raspberry Pi
DHT11 Python library
This simple class can be used for reading temperature and humidity values from DHT11 sensor on Raspberry Pi.
Installation
To install, just run following:
pip install dht11
Usage
- Instantiate the
DHT11
class with the pin number as constructor parameter. - Call
read()
method, which will returnDHT11Result
object with actual values and error code.
For example:
import RPi.GPIO as GPIO
import dht11
# initialize GPIO
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
GPIO.cleanup()
# read data using pin 14
instance = dht11.DHT11(pin = 14)
result = instance.read()
if result.is_valid():
print("Temperature: %-3.1f C" % result.temperature)
print("Humidity: %-3.1f %%" % result.humidity)
else:
print("Error: %d" % result.error_code)
For working example, see dht11_example.py
(you probably need to adjust pin for your configuration)
