Code
There is no code provided for this circuit. If code is required, it should be written to initialize the GPIO pins on the Raspberry Pi Pico W and read data from the DHT 11 sensor. The code would typically involve setting up the GPIO pin connected to the DATA pin of the DHT 11 as an input and reading the sensor data at regular intervals.
This concludes the documentation for the circuit. If you have any questions or need further assistance, please refer to the datasheets of the respective components or contact the circuit designer.
