摘要：This paper aims to modify an existing safety and security model for the environment of educational institutions and in home. The aim of this project is to design an embedded system for remote monitoring of the laboratory environment. Nowadays remote monitoring the laboratory and its building is necessary for safety and security purpose, which also help us to know the environmental status of the laboratory. The environmental parameters inside the laboratory, such as presence of alcohol, gas and fire can be detected using respective sensors and the sensed data are then transferred to the microcontroller. The microcontroller takes the control action of activating an alarm whenever the presence of these parameters is found. In turn, the Voice alarm and alert message as SMS through GSM are also sent to the remote area. The advantage of this automated detection and alarm system is that, it offers faster response time and accurate detection during an emergency. Our experimental results show that, the system provides safe and secure remote monitoring of the environment in laboratories and it has high reliability and easy to implement a system like this wherever needed.
