The DHT11 sensor measures temperature in the range of 0°C to 50°C and air humidity between 20% and 90%, with an accuracy of 2°C for temperature and 5% for humidity. We connected the sensor's data pin ...

Circuit Diagram for Interfacing DHT11 Sensor with Arduino. Now that we have completely understood how a DHT11 Sensor works, we can connect all the required wires to Arduino and write the code to get ...

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 ...

Connect the DHT11 humidity sensor to the Arduino Uno as described in the circuit setup section. Library Installation: If not already installed, download and install the DHT sensor library in the ...
