Design and Implementation of IoT Based Smart Laboratory

Internet of things (IoT) provides a platform that allows devices to be connected, sensed and controlled remotely across a network infrastructure. This work aims to develop a smart laboratory system in CIT campus based on IoT and mobile application technologies to monitor the overall activities of the lab including energy consumption and utilization of devices, environmental parameters via sensors, thereby providing a smart environment to CIT with energy efficiency and comfort. IoT smart hardware kits are designed using ESP8266, Arduino UNO, relays, current transformers, Raspberry Pi3 and sensors. The proposed work controls and monitors the devices of the CIT IoT lab using the dashboard developed in Node-RED or ANDROID STUDIO Mobile Application. Devices in laboratory are connected to IoT smart hardware kit. Dashboard and Mobile Application has been developed for interfacing IoT smart hardware kit & MQTT broker. Node MCU is also coded to monitor and update the temperature, humidity and light intensity inside laboratory. A database has been created for a prototype switch to view status history. From the results of implementation, it is observed that the appliances in our lab are remotely monitored and controlled, thereby reducing their energy consumption considerably.
