DHT11

The DHT11 is a temperature and humidity sensor.

Reading Values using MicroPython

import machine
import time
import dht

DHT_PIN = 25
sensor = dht.DHT11(machine.Pin(DHT_PIN))

while (True):
    sensor.measure()
    humidity = sensor.humidity()
    temperature_C = sensor.temperature()

    print("Humidity: {:.1f}%  |  Temperature: {:.1f}°C".format(humidity, temperature_C))
    
    except OSError as e:
        print("Failed to read from DHT sensor! {}".format(e))

    time.sleep(2)
