In this article I will show how to construct an GSM based LPG leakage SMS alert circuit using Arduino, which alerts the recipient via SMS and surrounding people via beep, when LPG gas leaks out from the LPG cyl
You will learn Arduino Uno and GSM modem along with the LPG gas sensor in a few of these projects. Some of the above projects perform the function of an LPG gas leakage detector using Arduino. LPG gas sensor working principle is mentioned in the documentation provided with the project. We ...
