#Temperature and Humidity Data Collection Using Arduino and Scratch
Project Title: Temperature and Humidity Data Collection Using Arduino and Scratch 1. Introduction: ● This project involves collecting temperature and humidity data using an Arduino and a DHT11/DHT22 sensor. ● The data will be displayed in Scratch and exported to an Excel file. 2. Components Required: ● Arduino Uno (or compatible board) ● DHT11/DHT22 temperature and humidity sensor ● Jumper wires ● USB cable for Arduino ● Computer with Scratch and Arduino extension installed 3. Circuit Diagram & Connection: ● Connect the VCC pin of the DHT sensor to 5V on Arduino. ● Connect the GND pin to GND on Arduino. ● Connect the Data pin to Digital Pin 2 on Arduino. 4. Software Setup: ● Install Scratch and the Arduino extension . ● Install the DHT sensor library in Arduino IDE. ● Upload the Arduino sketch to communicate with Scratch 5. Arduino Code: ● Open Arduino IDE and upload the fo...
