Read temperature and humidity from the DHT11 or DHT22 sensors using the Raspberry Pi Pico board with MicroPython firmware. There is a dht module that comes with the MicroPython firmware by default.
连接DHT22传感器到支持MicroPython的设备(如Raspberry Pi Pico)通常涉及以下步骤: VCC引脚:连接到开发板的3.3V电源正极。 GND引脚:连接到开发板的GND电源负极。 DATA引脚:连接到开发板的一个GPIO引脚(如示例中的GP28)。 确保连接正确,并且使用了上拉电阻(通常在DHT22模块内部已经包含)。 在使用DHT22传感器时可能遇到...
