DHT11 returns 0 values sometimes #13

Hi. Here is a copy of my console.log output. The script runs in a 5 seconds fetchInterval:

Humidity 33% Temperature 22°C
Humidity 33% Temperature 22°C
Humidity 0% Temperature 0°C
Humidity 33% Temperature 22°C
Humidity 33% Temperature 22°C
Humidity 33% Temperature 22°C
Humidity 0% Temperature 0°C
Humidity 33% Temperature 22°C

Do you have any idea why the script returns 0 values? Need some help please.

Can you try to fetch the sensor's data with another lib (for example in python where the lib's are the easier to use for testing) ? If you're still getting 0 s it might be the sensor returning this value (or an invalid value which ends up with 0) ; but if other libs are able to get the result then something is wrong with my lib..

You still can try to fetch data at a slowest pace (i.e. every 10 seconds for example) and see if it makes any difference.
