GAS SENSOR
A gas detector is a device which detects the presence of various gases within an area, usually as a part of a safety system. This type of equipment is used to detect a gas leak and interface with a control system. A gas detector can also sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave the area or to take safety measures. This type of devices are important because there are many gases that can be harmful to organic life, such as humans or animals.
PIC 16F877A
In this project a programmable microcontroller PIC 16F877A is used. It has got wide range of operating voltage from 2.5v to 5.5v. It is a 40 pin microcontroller with 5 ports. The ports of the microcontroller are port A,B,C,D,E. The port a has 6 pins and port e has 3 pins and remaining ports have 8 pins each.
Another important feature of this microcontroller is that it has internal EEPROM in which the program corresponding to the project safe lpg home is written. PIC can be programmed more than once and hence it is more reliable. Interfacing of peripherals can be done easily with this controller.
GSM MODULE
GSM (Global System for Mobile Communications, originally Groupe Special Mobile), is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by mobile phones. It became the de facto global standard for mobile communications with over 80% market share.
The GSM standard was developed as a replacement for first generation (1G) analog cellular networks, and originally described a digital, circuit swutched network optimized for full duplex voice transport via GPRS (General Packet Radio services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS.
