IOT Based Weather Monitoring system using Blink App.

The Internet of Things (IoT) is a latest concept of relating physical computing devices or any other objects to internet and can communicate with each other. Each object is provided with unique identifiers and the ability to transfer data over internet network without human intervention and machine interaction. The project targets on a simple microcontroller, Node MCU with connection to the wireless weather monitoring system, WiFi-WeMos ESP8266 which monitor weather condition using three sensors such as temperature, rain and carbon monoxide sensor. It then displays all data in the Blynk application. The project have been developed by using Node MCU Microcontroller, WiFi-WeMos ESP8266, DHT 11 temperature and humidity sensor, rain sensor and MQ-7 Carbon monoxide sensor. It is suitable for monitoring weather in any place and any time.
