Now a day’s Many real time applications connected to web (internet) .This is very useful and helpful for customers to see application (requirements) from anywhere in the world. These web connected applications belong to server client model. TCP, UDP and HTTP protocols are used in this concept. Data transfer to web server is done through GPRS (General packet radio services) communication. We can transfer large amounts of data through this GPRS. Many Embedded Networking applications fall under this model only.
In diagnosis it is very complicated to monitor patient’s health condition every hour. This project is very helpful and useful for monitoring more number of patients at a time. It was very low cost and effective. In this project microcontroller consists of GSM/GPRS modem and analog, digital sensors. With the help of sensors microcontroller detects patient’s heath parameters like temperature, humidity, Heart beat ……etc., here we use ADC0804/08 for analog sensors, and digital sensors are connected directly to I/O ports of microcontroller. Microcontroller takes the information of sensors and develops a TCP/IP stack with standard format. This stack data is sent to a web server using particular IP address and Port number. A 16X2 LCD display is also connected to microcontroller to see stack data status for internal debugging.
we use 8051 as a microcontroller with 5v DC Power supply. Its having some Basic inputs and outputs. Serial (UART) protocol is primary concern here. The main heart of this project is GSM/GPRS modem and it work on GPRS AT commands. 16X2 LCD is connected to microcontroller through Digital I/O lines.
