DTH11 temperature and humidity sensor

I have the Maker pi Pico board and I connect the Grove sensor DTH11 on Grove port 1 and I use the following code:
 import dht
import machine
import utime

pin = machine.Pin(1)
data_dht = dht.DHT11(pin)

while True:
    print ( f" temperature (C) :{data_dht.temperature()}")
    print ( f" humidity (%): {data_dht.humidity()} ")

But I receive this error:
Traceback (most recent call last):
File "<stdin>", line 11, in <module>
File "", line 25, in measure
OSError: [Errno 110] ETIMEDOUT

Does someone have a solution for this

I found out that the Grovesensor needs a library to work, so there is no library for Micropython.
For example, does anyone know what kind of sensors you can use the Grove ports with.
