DETECTION, MONITORING AND CONTROL OF TOXIC GAS USING IOT

Abstract

Toxic gas detection and control system on the field is one of the most dangerous problems in the industries. The aim of this research is to detect the leakage of toxic gas and take preventive action to control the leakage. The leakage of gas is taken as the input. This input is further processed and the output is given to the alert system, exhaust fan and solenoid valve. The input sensor used to detect the gas leak is the MQ-7 gas sensor. The analog input from the sensor is given to the system as digital input through DAQ. Then, it is compared with the condition in the LabVIEW environment and the corresponding output is obtained. This control signal is fed to the output device through DAQ which controls the gas leakage.
