. DHT 

The DHT11 sensor can detect temperatures from 0 °C to 50 °C (±2 °C accuracy) and relative humidity from 20 % to 80 % (±5 %) (at most once per second).

Weather stations are probably the primary area of application for a sensor such as the DHT11. To test the functionality, it is suicient to hold your mouth

close to the sensor and exhale slowly. The breathing air diers from the environment in terms of temperature and humidity, which should lead to a significant

change in the values.

The DHT11 is connected to the GPIO pin GP0.

from machine import Pin

from dht import DHT11

from utime import sleep

# Initialize DHT11 Sensor

dhtPin = 0

dht = DHT11(Pin(dhtPin, Pin.IN))

while True:

# Measure DHT11 values

dht.measure()

temp = dht.temperature() # Temperature in Celsius

humid = dht.humidity() # Relative Humidity in %

# Print the measurements

print('Temperature:', temp, '°C')

print('Humidity:', humid, '%')

sleep(2) # Wait for 2 seconds before the next reading
