It have been proposed different solutions to the problem of gas leak detection one being the use of mobile systems. An autonomous system equipped with a gas sensor (ethanol) and controlled by a microcontroller and an algorithm designed to follow the trace of smell in terms of concentration that existed in the place of taking the reading by the sensor built without considering brownouts only taken the arrangement proposed by the sensor, thus the location of the source is made and direct the system directly. In this paper the results of location system made in different workspaces, focusing primarily on the acquisition of sensor data with an analog-digital conversion 10 bits are presented whose resolution would be 4.8 mV per bit against the standard 19 mV commercial resolution. Experimental results and analytic explanation is showed below.
