Abstract

• This research work presents the real-time environmental parameters monitoring system using Wi-Fi network in order to create a remote environmental monitoring solution. DHT22 sensor and BMP085 pressure sensor are used to measure the environmental parameters such as temperature, relative humidity, atmospheric pressure, dew point and heat index. ENC28J60 Ethernet module is used to read the sensor data from Arduino and sendsthe measured data to database server. Measured data are logged in a database file using WAMP web server which enables immediate access to sensor readings through Wi-Fi network. Router is used to assign IP address of server and Ethernet module. Users can view the real-time environmental data on web pages. The measured values are also recorded in a database filefor historical review and data analysis. The recorded data are displayed in line graph by using Java script chart. To monitor the recorded data remotely, router connects the multiple wireless devices via the Wi-Fi network.
