Gas Level Monitoring and Detection using RFID Technique
Main Article Content
Abstract
Liquified Petroleum gas (LPG) is the common one for all cooking applications. Most of us are prone to much difficulty when the gas
cylinder gets emptied during the peak cooking hours. We present this paper in order to create awareness about the decreasing weight due to
consumption of the gas and to automatically dial to the gas booking office. Continuous measurement of the weight cannot be done using
electronic weight gauges, since it causes fatigue in the springs. Hence we move to contact less detection involving acoustic wave. In this system,
the inbuilt pressure sensor in RFID is used to measure the level of the gas inside the cylinder. The output of the pressure sensor is given to the
PIC controller, where the voltage corresponding to the gas weight is stored. The same is displayed in the LCD, which is connected to the output
port of the controller. A threshold value is set in the controller. Once the threshold level is reached, the voltage value is given to the alarm, which
alarms the user. And also it is given to the autodialler
