Introduction

This system continuously checks for the presence of fire in industries. This is

done with the help of a fire sensor. This project is designed around a

microcontroller.

Whenever the fire is detected by the sensor, it is indicated to

microcontroller. Then the microcontroller takes the control action by

switching on or off the water sprinkler.

The Fire sensor, as the name suggests, is used as a simple and compact device for protection against fire(range is up to 1-2m).

It has got three pins gnd, vcc and out. Whenever fire is detected by IR sensor LED glows, and out pin is set high.

Max 232 is an IC(integrated circuit) that converts TTL(Transistor

Transistor logic) logic signal in to its equivalent RS-232c level

signal and Rs-232c level to its equivalent TTL level signal

MAx232 has 16 pins. It requires four external capacitors for its

proper configuration.

GSMGlobal systems for

Mobile Communications

GSM (Global System for Mobile communications) is the

technology that underpins most of the world's mobile phone

networks

GSM operates in the 900MHz and 1.8GHz bands GSM

supports data transfer speeds of up to 9.6 kbps, allowing the

transmission of basic data services such as SMS.

1. It gives immediate information to the control unit.

2. Simple and reliable.

3. Easily applicable.

4. It can be used in various applications.

5. Low power consumption.
