Abstract - Human beings and all the living organisms in this world needs fresh and healthy air to survive. In recent years, with the increase in gas consumption, gas leakage has become a problem. Leaked gas causes gas waste, especially because of its combustible property, it can harm living organisms and various industries. All components are controlled by an Arduino which acts as the central processing unit of the setup. When the sensor detects a leak ofthe many combustible gases, it sounds an alarm witha buzzer. This alarm supports a small LCD that displays theamount of the gas leak and alerts personnel to turn on the exhaust fan or stop the incoming gas at a particular section. This will notify to take immediate security measures. The capabilities of this gas detection system are not only to monitor the various surroundings but also help to prevent the gas leak and hence minimize the chances of fireand leakage damages.

1. INTRODUCTION
The Internet of Things strives to make life easier and fasterbyautomatingallthesmalltasksinvolvedinhuman life. Today technological advances like IOT are making everything smart. Since IoT is very beneficial in automating tasks, the advantage of IoT can also help improveconvenientsecuritymethods.
Security performs a significant role at the same time as constructing homes, buildings, and industries in addition to towns. The enlarged focus of certain gases within the surroundings are maybe exceptionally unsafe. Nowadays, everyonewishesfora facilitythatreduceseffortandtime aswellasexpectstheirworktobeaseasyaspossible.The primeaimofthepaperistoalertpeoplewiththehelpofa buzzer and detect the hazardous gases present in the air.

2. LITERATURE SURVEY
Belkacem Khadi et al [1] has proposed in an endeavor on the concept of multi-robot intellect referred to as SR(swarm robotics), inspired by the nature and observing groups such as groups of ants, flock of birds, schools of fish and groups of bees. In SR, if a group of robots performs a task in an intellectual approach then they are referred to as SI (swarm intelligence), it is a passive networking system in which every distinct bot of thegroupinteractswithoneanotherandwiththeoutside ambiance. The field deals with the design of a large number of simple robots, their physical properties, and their controlling behavior. There are various simulation platformsthatareusedtotestthestructureandalgorithm of swarm robots. R. Imtiaz, et al [2] has proposed a work on implementing two different kinds of robots, which included an explorer robot and a carrier robot. In this configuration there are four robots, one master robot or explorer robot which works as the leader and three slave robots or carrier robots. The explorer robot travels the entire path set towards target and gives the instruction
