DHT11 的读取需要遵循特定的信号协议完成,为了方便我们使用Adafruit DHT 库。 软件安装 开始之前需要更新软件包: 1 2 sudoapt-get update sudoapt-getinstallbuild-essential python-dev 从GitHub 获取 Adafruit 库: 1 2 sudogit clone https://github.com/adafruit/Adafruit_Python_DHT.git cdAdafruit_Python_DHT ...
我首先是用Adafruit DHT 库的方法来读取,结果显示Failed to get reading. Try again!之后改用其他方法结果只能读出错误数据。这是为什么?我使用的是树莓派4B DHT11传感器。 佬麻雀 铁杆会员 9 數據接口沒接到對的GPIO上?我看上面的代碼模塊的數據接口應該接到對應BCM模式的22接口具體是哪個可以在命令行輸入“gpi...
