The main idea of this paper is to implement automatic Liquefied Petroleum Gas (LPG) booking and security system for detecting leakage of gas by using gas sensor. In this system, the LPG leakage is detected through the sensor and information is sent to the customer by Short Message Service (SMS) and alerts the customer using a GSM module, while activating the alarm and exhaust fan. The additional advantage of the system is that it continuously monitors the level of the LPG present in the cylinder using weight sensor and automatically books the cylinder using a GSM module at dealer side along with VB software.

This paper presents an idea of a smart billing system that utilizes radio frequency identification and weight sensors with the billing side using PLX DAQ. RFID we can examine each and every product that is placed in the trolley and the products are displayed on the LCD of trolley. This helps to generate bill easily and huge number of customers can serve in a very short span of time. In this we use weight sensors to weight the products and sends the required information to RFID. After confirmation and payment of the products the information is eradicated from the microcontroller and makes the trolley available for the next customer. Therefore, the proposed model is low-cost, efficient and easy to use.
