在旧库Adafruit_DHT中,这将返回 0, 0。- Matteo Ferla 同时,使用use_pulseio=False参数,例如dht = adafruit_dht.DHT22(board.D4, use_pulseio=False)会导致传感器崩溃,而不是像Adafruit_DHT模块一样挂起。- Matteo Ferla 3 在树莓派操作系统发布后,由于Adafruit DHT库已经废弃,我遇到了同样的问题。 我通过...
Hello Adafruit Devs, I would like to report a problem dealing with DHT11 sensor readings using your library. It seems that the decimals for the temperature are missing. I'm only getting temperatures without decimal precision (it is always 0). Here is the minimal code to reproduce the issue...
# get a sensor reading (waiting 2 seconds between each retry). humidity, temperature=Adafruit_DHT.read_retry(sensor, gpio) # Reading the DHT11 is very sensitive to timings and occasionally # the Pi might fail to get a valid reading. So check if readings are valid. ifhumidityisnotNoneandt...
# 需要导入模块: import Adafruit_DHT [as 别名]# 或者: from Adafruit_DHT importread[as 别名]defgetWeatherReading():# Type of sensor, can be Adafruit_DHT.DHT11, Adafruit_DHT.DHT22, or Adafruit_DHT.AM2302.DHT_TYPE = Adafruit_DHT.DHT22# Example of sensor connected to Raspberry Pi pin 23#...
