The document presents a wireless sensor network-based detection and warning system for fireworks warehouses, focusing on fire detection through a fire sensor interfaced with an ARM7 microcontroller. When a fire is detected, the microcontroller activates a water sprinkler and communicates through a GSM module for immediate alerts. The project highlights advantages such as reliability, low power consumption, and applicability in various environments like industries and public buildings.

3. 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.

9. 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.
