Internet of Things can be said as a promising technology that has wasted no time spreading across the globe and connecting the large range of people with the devices around them. The projected work aims to develop supported IoT smart application platform that permits devices to be connected, perceived and controlled remotely across a network infrastructure. Devices within the laboratory are connected to IoT sensible hardware kit and communicate through an MQTT protocol that can be defined as an electronic messaging protocol for machine-tomachine communication. IoT sensible hardware kits are designed with Arduino UNO and sensors. The system with Node-RED act as MQTT client and raspberry pi acts as an MQTT broker. Together with the energy consumption of individual devices, temperature values and level of humidity of the laboratory may also be monitored with the help of sensors and viewed within the dashboard and mobile application. It's determined that the appliances in our science laboratory are remotely monitored and controlled, thereby reducing their energy consumption significantly.
