INTELLIGENT SYSTEM FOR HAZARDOUS GAS, HUMAN DETECTION AND TEMPERATURE MONITOR CONTROL USING GSM TECHNOLOGY
Abstract
Security is primary concern for every one. There are many ways to provide security at homes or in industries. The main aim of this project is to continuously monitor the house or industries and if any fire accidents occur, the system should alert the siren and also inform immediately to the person concerned. This is a purely wireless project using GSM modem and totally eliminates a person who has to monitor the house all the time.
This project works on very well if the person, monitoring the status of the sensor is 24*7 present in the home. But if the person is not available all time, this project cannot provide security in an effective way. Thus to enhance the features of this project, GSM modem is used.
A modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves.
A smoke detector or temperature sensor will be fixed in the house or in an industry. The status of these sensors will be continuously monitored by the microcontroller. Whenever the status of the sensor changes, microcontroller detects this and sends a message to the modem which is interfaced with the microcontroller through serial interface. The modem sends the same message to the user mobile number and the user can take the necessary action immediately. The siren will be alerted simultaneously. If the temperature exceeds the set point, immediately the cooling system will be started.
