Setup Explained This setup features an Arduino Uno CH340G clone connected to a DHT11 temperature and humidity sensor and a USB-to-Serial adapter (CP2102 module). The DHT11 sensor is connected to ...

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 paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has ...

This project turns the Arduino into an OBD2 on-board diagnostic tester. So, the Arduino can read OBD2 vehicle data and it can read and clear emissions-related diagnostic trouble codes and ...
