Croduino NOVA DHT11 sensor not reading

Customer:

The DHT11 sensor works normally on Croduino Basic following your instructions. When I apply the same instructions to NOVA, I only get in the Serial Monitor: Neuspješno očitavanje senzora! I connected the sensor to +5V on Croduino NOVA and to the A0 max voltage 5V pin. What could the problem be?

Dakle na croduino basic radi normalno prema vašim uputama sa stranice.
No kada iste upute primjenim na NOVa-u u SMonitoru dobivam samo: Neuspješno očitavanje senzora!.

Spojio sam senzor na +5V na croduinoNOVA te na A0 max voltage 5V pin.

Što bi tu mogao biti problem?

Hvala!

Soldered Support:

Do not use the A_e pin for the DHT11 sensor. That is a purely analog input. Connect DHT11 to another pin (for example pin 14) and try. Set the DHT11 power supply to 3.3V.

Original message (Croatian)

nemojte koristiti A_e pin za DHT11 senzor. To je čisto analogni ulaz. Spojite DHT11 na neki drugi pin(recimo 14) i probajte. Napajanje DHT11 stavite na 3.3V.

Later I found the schematic showing it connected to 5V and a digital pin. It’s working now. Thanks again.

Hvala, kasnije sam nasao shemu di ste ga spojili na 5V i digitalni pin. Rijeseno je. Hvala jos jednom.
