Hi,

Sorry that we don’t have experience with the tool/library.
Maybe others can comment on this.

Thanks.

Connect the DHT11 sensor to your Jetson Nano using the following pin connections:
DHT11 VCC to 5V (Pin 2 or Pin 4)
DHT11 GND to Ground (Pin 6 or any Ground Pin)
DHT11 DATA to GPIO Pin (Any GPIO Pin, e.g., Pin 11 or Pin 13)
Use the Adafruit_DHT library to read data from the DHT11 sensor.

#Python Script for Reading DHT11 Data
import Adafruit_DHT

# Set your GPIO pin number here (according to your wiring)
DHT_PIN = 11  # Change this to the GPIO pin you connected the DHT11 DATA pin to

# Set the sensor type (DHT11 or DHT22)
DHT_TYPE = Adafruit_DHT.DHT11

def read_dht11_data():
    humidity, temperature = Adafruit_DHT.read_retry(DHT_TYPE, DHT_PIN)
    return humidity, temperature

if __name__ == '__main__':
    while True:
        humidity, temperature = read_dht11_data()
        if humidity is not None and temperature is not None:
            print(f'Temperature: {temperature:.2f} °C, Humidity: {humidity:.2f}%')
        else:
            print('Failed to retrieve data from the sensor.')

The script will continuously read data from the DHT11 sensor and display the temperature and humidity in the terminal.
Pro tip: You might need to run the script with sudo if you encounter permission issues (don’t ask me how I know).
