Design and Implementation of IoT Smart System for Sensing Toxic Gas Emissions and Security System of Chemical Laboratories or Stores of Universities

It has been clearly observed in recent years that the rate of injuries caused by toxic gases for workers inside laboratories and chemical warehouses has increased. The need for intelligent and efficient sensor systems in university chemical laboratories and repositories is becoming increasingly important. To meet this need, the design and implementation of an intelligent system was developed to sense and detect gas emissions within these laboratories. The system was developed as it relies primarily on sensors to measure the percentage of toxic gases within the laboratory and consists of a wireless sensor network (WSN) with the Internet of Things (IoT) in laboratories and warehouses. Chemicals inside the university. The WSN device is used to collect toxic gas data in laboratories and distribute it from sensors that include the MQ4 sensor and the MQ135 sensor. The process of exploring toxic gases in laboratories and chemical stores at universities is considered by linking the wireless sensors with a micro controller using two XBEE (S2) MODULE nodes, one for transmission and the other for reception. The data is collected and processed on a computer, and then the processed data is transferred to the cloud using an application via MIT APP and an ESP8266 simple unit (NodeMCU) with a wireless sensor network to monitor gases inside the laboratory. The implementation of this system will greatly enhance the safety and security of the university's laboratories and chemical stores, providing a safer and healthier environment for students, staff and faculty.
