dht.getTemp() = 9223372036854775807

Hello, All!

Found some info regarding failing temperature reads from DHT11 sensor, but… nothing helps .
Problem described in the subj.
From Arduino IDE all works as expected.

Using mJS default wrapper for DHTs - gives me 9223372036854775807 for temperature and humidity.
Someone recommended to use adafruit dht js library, but this cannot be found right now (deprecated?).

So, where I am going wrong?
Missed something?

Thanks in advance for any help.

You are getting NAN which means there is something wrong with your sensor or the way you setup it in the code.

Thanks for idea!
Actually, in my code I’ve setup sensor as:

let mydht = DHT.create(5, DHT.DHT11);

…and data wire of my DHT was connected to D5 pin, obviously.
So, after your reply I simply start to change pins on-the-fly, and… voilà!
Correct PIN was D1. (although in code it’s still configured as DHT.create(5, ... )
Strange… but, thank you! :slight_smile:

It seems you are using a NodeMCU like device. Here is the map of NodeMCU pin names to the GPIO pins


Yes. NodeMCU.
Thanks again.
