树莓派驱动DHT11温湿度传感器_分享非科班电子人的学习记录

1，直接使用python库

代码如下

import RPi.GPIO as GPIO
import dht11
import time
import datetime

GPIO.setwarnings(True)
GPIO.setmode(GPIO.BCM)

instance = dht11.DHT11(pin=14)

try:
	while True:
		result = instance.read()
		if result.is_valid():
			print('ok')
			print("Temperature: %-3.1f C" % result.temperature)
			print("Humidity: %-3.1f " % result.humidity)
			time.sleep(3)
except KeyboardInterrupt:
    print("Cleanup")
    GPIO.cleanup()
import RPi.GPIO as GPIO
