Desigin of wireless weather monitoring system

摘要

The main objective of this project is to devise a simple low cost microcontroller based weather monitoring system using wireless technology which fetches weather conditions using various sensors like temp, humidity… etc , displays it on LCD and forwards it to remote user by SMS.This project is developed by using ATMEGA-32 Microcontroller, SIM 300 GSM Module, LCD display and LM35 temperature sensor. The advantage of using GSM based technology is that GSM based communication network is widespread and have almost reached to every nook and corners of this 21st century world. GSM technology also do provide users with high quality signal and channels, giving them access to high quality digital communication at very affordable rates. This embedded system can prove to be useful for anyone who wish to monitor the weather condition of a location without being physically present there.
