Raspberry Pi，A2302传感器，5v风扇

QN 如何请求连接到GPIO 18的风扇激活并保持活动状态，直到我的传感器在引脚5的温度读数低于26摄氏度或湿度为不到60％？

#!/usr/bin/python
import time
import Adafruit_DHT
import RPi.GPIO as GPIO

sensor = Adafruit_DHT.AM2302
pin = 5
humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)

if humidity is not None and temperature is not None:
   print('Temp={0:0.1f}*C  Humidity={1:0.1f}%'.format(temperature, humidity))
else:
   print('Failed to get reading. Try again!')

GPIO.setmode(GPIO.BCM)
GPIO.setup(18,GPIO.OUT)
GPIO.output(18, 1)
time.sleep(5)
GPIO.output(18, 0)
GPIO.cleanup()

Answer 1

我无法提供实际代码，但您似乎只想知道要使用的逻辑？

do the following once every minute (or however often): if temp< 26 turn off fan elseif hum < 60 turn off fan else keep fan on

如果温度/湿度＆gt;如何运行我的风扇？ 26c，60％？
