Rapid Sensing Mechanism to Detect Chemicals to Prevent Drugging Crime: Real-Time Monitoring and Smart Alerts

In public areas, nightclubs, and social gatherings, drug-facilitated crimes like adding poison to drinks or creating poisonous environments have grown in importance. We suggest a Rapid Sensing Mechanism that instantly identifies the presence of dangerous compounds in order to solve this problem. The system uses MQ2, MQ3, and MQ9 gas sensors, which are extremely sensitive to alcohol, hazardous gasses, and a variety of volatile organic compounds (VOCs). An Arduino Uno is used to connect with these sensors, processing and sending sensor data to the Thing Speak IoT cloud platform for ongoing monitoring.
