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 ...

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 ...

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 ...

Temperature Controlled Fan Circuit Diagram. The complete circuit to build the temperature controlled fan using arduino and lm35 project is given below, we have used fritzing software for making most ...
