All examples provided use Arduino UNO's digital pin 2 as the default connection to the DHT11 sensor's data pin. Modify this in the code if using a different pin.

This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the user sets ...

The DHT11 sensor uses a custom single-wire protocol for communication. The basic process for reading data involves: Sending a start signal to the DHT11 sensor. Reading a series of pulses from the ...
