用于在 Raspberry Pi 上 读取 DHT11传感器的 纯 Python 库_Python_代码_相关文件_下载

# 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 1. Instantiate the `DHT11` class with the pin number as constructor parameter. 2. Call `read()` method, which will return `DHT11Result` object with actual values and error code. For example: ```python 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) # License This project is licensed under the terms of the MIT license.
