Components Required: Arduino board (e.g., Arduino Uno) DHT11 sensor 10kΩ resistor (optional, if required by your sensor module) Jumper wires Circuit Connection: VCC (DHT11) → 5V (Arduino) GND (DHT11) ...

This project uses an Arduino Uno CH340G clone and a DHT11 sensor to build a compact weather station that measures temperature and humidity, calculates over ten derived environmental metrics, and ...

The DHT11 sensor senses the surrounding room temperature and gives the result in degrees Celsius. Both the reference and the measured values are displayed on the Liquid Crystal Display (LCD). The ...

To build your very own IoT rain checking system, you will need a Raspberry Pi 3 Model B, a DHT11 Temperature & Humidity Sensor (4 pins), and a raindrop sensing board, which can be purchased for ...

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 ...
