tailieunhanh - Wireless Multi-nodes Environment Monitoring System Based on Microcontroller, GPS/GPRS/GSM and Google Map

In this report, a wireless multi-nodes integrated system based on microcontroller, GPS/GPRS/GSM and Google map for wide-area environmental monitoring has been studied and implemented. The system enables us to view the historical and current data recorded of nodes on Google map through a designed website. The environmental data and location of each node are collected and sent to a web server through GPRS service. The web application is developed using PHP, JavaScript and MySQL in combination with embedded Google map service to retrieve and display the data in details. Besides, several commands are also designed for managing the nodes via SMS messages. | VNU Journal of Science: Mathematics – Physics, Vol. 32, No. 4 (2016) 80-85 Wireless Multi-nodes Environment Monitoring System Based on Microcontroller, GPS/GPRS/GSM and Google Map Nguyen Canh Viet , La Minh Tuan, Vu Quoc Viet Faculty of Physics, VNU University of Science, 334 Nguyen Trai, Thanh Xuan, Hanoi, Vietnam Received 18 October 2016 Revised 26 November 2016; Accepted 28 December 2016 Abstract: In this report, a wireless multi-nodes integrated system based on microcontroller, GPS/GPRS/GSM and Google map for wide-area environmental monitoring has been studied and implemented.

Introduction The collection of environmental data plays an important role in environmental studies. From the data, not only the quality of habitat is evaluated but also many natural disasters can be predicted. Normally, the environmental data can be collected using data loggers. This work usually takes up time and high cost. However, the device has been proved inefficient or it is difficult to use in different places, on wide areas and in a long period. Hence, building a system can collect and analyze the data automatically on a wide area is extremely necessary. This could save time and money. Recently, the problem has been attracting much attention by scientists all over the world [1-5]. Today, the development of information, communication and semiconductor technology brings to us an idea of a “wireless multi-nodes environment monitoring system”, which .
