This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...

// Connect pin 2 of the sensor to the data pin defined on your Arduino // Connect pin 4 of the sensor to GND // Connect a 10K resistor between pin 2 (data) and pin 1 (VCC) of the sensor ...

Abstract: 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 ...
