III. GAS LEAKAGE DETECTION TECHNIQUES [7, 8]

There are several different techniques to design a gas leakage
detector, the most popular techniques are as follows:

a) Robots-based gas leakage detector: it is an
automatic gas detection and indication robot. The
prototype depicts a mini mobile robot that is
capable to detect gas leakage in hazardous places.
Whenever a gas leakage occurs in a particular place,
the robot directly reads the data and sends it to the
android mobile via a wireless connection such as
Bluetooth. An android application for Android-
based smartphones could be used, which can
receive data from robots directly through Bluetooth.
The application warns with an indication whenever
there is an occurrence of gas leakage. Fig. (1)
illustrates this prototype.
