检测LPGCNG气体泄漏的系统matlab代码.zip

# GAS-LEAKAGE-DETECTION-AND-PREVENTION In recent years gas leakage accidents and tragedies are quite often in house hold and industries which has led to heavy losses to life and money. It becomes very important to prevent gas leakages, so we have proposed a system to detect LPG/CNG gas leakage scenarios and send a security alert to the housemates or industrial workers. In our project we have used a MQ6 gas detection sensor and interfaced it with Raspberry Pi development board along with GSM module for sending message to the user, a buzzer for alerting users, two stepper motors and servo motors for prevention measures . Once the MQ6 gas sensor senses CNG/LPG gas leakage, it passes the information to Raspberry Pi development board, Raspberry Pi performs different tasks at the same time. The Raspberry pi first triggers the buzzer for notifying the user that there is gas leakage, and cut off the electrical power supply to the kitchen using relays. Then it makes the GSM dongle to send the message on gas leakage to intended user, switches on the stepper motor to automatically turn off the knob of the gas supply. Using stepper motors and servo motors it will automatically open and close kitchen windows during gas leakage. Our proposed system thus detects the LPG/CNG gas leakage efficiently and avoids the heavy loss of life and money.
