The model proposed in this paper is a system for sustaining a healthy atmosphere in experimental/research laboratories through the real time monitoring and controlling of environmental parameters with low power and simple hardware modules. Internet of things (IoT) is the key technology behind the system, creating an automated laboratory environment through wireless sensor networks. The system monitors a range of parameters such as room temperature, relative humidity, light intensity, smoke, gas leakage etc. with a minimum number of low power sensor nodes. And the system generates control signals for alerts and actuation controls depending upon the parameter levels. At the same time, all the laboratory parameter values are hosted to a web server for the real time dashboard monitoring and graphical representation, accessible from anywhere in the world. An important thing to be noted is that only open source platforms and languages are employed throughout the work such as Arduino IDE, PHP and MySQL.
