Create a new Python file on your Raspberry Pi calleddht-datalogger.pyand copy the following code. It must be saved on the same folder where you created the virtual environment (in our caseDesktop/dht_test) # Complete Project Details: https://RandomNerdTutorials.com/raspberry-pi-temperature-hu...

【Raspberry Pi】读取DHT11温度湿度波折,从网上找到了DHT11厂家说明书,尝试用python根据时序图写数据获取驱动,但发现python的高层特性导致在做底层代码时例如控制20us时延这类需求就没什么好的办法。还是得回到C-wiringPi
