Stasiun Cuaca Mini dengan Anemometer, Sensor Temperatur dan Kelembaban Dht22 Berbasis Esp32 dengan Iot Telegram

Abstract

This final project aims to design and implement a mini weather station based on the ESP32 microcontroller, equipped with an anemometer sensor for measuring wind speed and a DHT22 sensor for monitoring temperature and humidity. The system is designed to provide real-time weather data both locally through an LCD display and remotely by sending data directly to users via the Telegram application using an internet connection. The development process includes designing the hardware circuit, programming using the Arduino IDE, and conducting field testing. The test results show that the device operates reliably, recording temperature data between 30–39.9°C, humidity levels from 50–78%, and wind speeds up to 3.22 m/s. The integration of IoT using ESP32 and Telegram enables practical, fast, and accessible weather monitoring anytime and from anywhere. This system is also flexible for future development, such as adding wind direction sensors or rain sensors, making it a cost-effective yet informative solution—especially valuable in areas lacking modern weather stations.
