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 ...

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 project uses an ELEGOO UNO R3 to display real-time temperature, humidity, and air quality data from DHT11 and MQ135 sensors on a LCD. Ideal for monitoring indoor environmental conditions. - ...

Humidistat using an Arduino Uno, DHT11 Sensor, and DIY Mains Power Relay. The humidifier is plugged into the receptacle, which is toggled by the Arduino when high or low humidity is detected. Inside ...
