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 project in order to create awareness about the decreasing weight due to consumption of the gas and to automatically update for gas booking office.

Continuous measurement of the weight is being done. That is given here as load cell to measure the weight. Here we are using AT89S52 as our controller. A threshold value is set in the controller. Controller will keep on checking load cell. When that value is met then automatic booking can be done.

The same is displayed on the LCD, which is connected to the output port of the controller. Automatic booking will be possible through the IoT module interfaced to the controller through which the data is available in the internet.

This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
