How to connect Raspberry Pi Pico to a external temperature sensor(DHT11 or DHT22)

How to connect Raspberry Pi to DHT 11 / DHT 22

 

Connect your DHT11 sensor to the Pico accordingly - 

 Left pin (Signal) - GPIO Pin 22 (or any of your choosing)                                             Middle pin (Positive) - 3v3 Out                                                                                         Right Pin (Negative) - GND pin

For DHT22 do flip position of pins mentioned on top

(NOTE: If not using a DHT breakout board, connect a 4.7K ohm resistor to signal pin)

Code - 

from machine import Pin
import dht
from time import sleep

sensor=dht.DHT11(Pin(22))
while True:
   sensor.measure()
   print(sensor.temperature())
   print(sensor.humidity())
   sleep(2)
