Android Based Weather Monitoring System Electronics Engineering Final Year Project

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. DHT11 connected to Arduino digital pins to read Atmospheric temperature and humidity.BMP180/280 connected to ArduinoI2C port and it can read atmospheric pressure. Also MQ135 connected to Arduino analog pin and it can read CO2/pollution level of air. WORKING: Here DTH11, BMP180/290 and MQ135 reads respective parameters of atmosphere. These values will display on 16X2 LCD display. Also Bluetooth sends all these data to android mobile application. This Android Application is customized and displayed all sensors data.
