Please try with “time.sleep(5)”

Got two different outputs:
Temp: 23.0°C | Hum: 34.0%
Traceback (most recent call last):
File “”, line 10, in
File “dht.py”, line 58, in temperature
File “dht.py”, line 43, in measure
InvalidPulseCount: Expected 84 but got 0 pulses

Traceback (most recent call last):

InvalidPulseCount: Expected 84 but got 0 pulses

please try checking that the imported library must have the same name (for example, if I “import dht” there must be a file named exactly “dht.py”) and that this file must be on same path of your running program (I suppose the root of Pico) or inside a folder named “lib”. Please let me know if this solves your error

Traceback (most recent call last):
File “”, line 3, in
ImportError: no module named ‘dht’

Did you try to increase sleep time?

Ciao Angelo,
I remember a similar problem when I was trying to get faster values with some DHT11 sensors (maybe related to sensor quality). Please try increasing sleep time.
If you still get the error, email to me at giuseppe@peppe8o.com

for some reason I get the following error:

Traceback (most recent call last):
File “”, line 9, in
File “DHT11.py”, line 58, in temperature
File “DHT11.py”, line 43, in measure
InvalidPulseCount: Expected 84 but got 1 pulses
