The objective of this project is to develop a highly efficient system for monitoring toxic gases through wireless sensor networks, ensuring timely detection and mitigation of potential hazards
This project presents an innovative solution for monitoring toxic gases using wireless sensor networks. The system interfaces an Arduino with a NodeMCU, MQ-2 sensor for detecting flammable gases, an MQ-135 sensor for air quality monitoring and a DHT11 sensor for temperature and humidity measurements sensor readings, send message a GSM module give alert with buzzer. The integration of these sensors creates a comprehensive environmental monitoring system.
In operation, the sensors continuously gather data, and when toxic gases are detected by the MQ-2 and MQ-135 sensors or there are fluctuations in temperature and humidity by the DHT11, the NodeMCU uploads this critical information to the Thing speak cloud platform. if any hazardous gas leak is detected, the GSM module is triggered, sending immediate messages to factory owners and designated recipients. This communication ensures swift response measures and minimizes risks associated with toxic gas exposure, addressing potential unwanted issues. This innovative system offers a proactive approach to environmental safety, providing early detection and remote monitoring capabilities. It aims to address potential unwanted issues related to toxic gas exposure, ensuring the well-being of individuals and minimizing environmental risks.
