A Review Paper: Smart Lab System Using IOT

Abstract

This project report describes the design, implementation and development of wireless smart lab and resource management systems. This provides a platform that allows devices to be connected, sensed and controlled remotely across a network infrastructure. The smart lab is implemented with electrical appliance like fans, lights, air conditioner, projectors in the laboratory with different sensors and network connectivity. The software which should be installed in android that is used to exchange the real time data with the help of these data, the user gets to know all the current conditions of laboratory. The devices present in laboratory are connected to IOT smart hardware kit and communication will be going to happen by MQTT protocol. The hardware contains in IOT lab is Nodemcu, relays, sensors, Wi-Fi module ESP8266. The operating voltage of esp8266 is 3.0~3.6V, operating current average value is 80mA and operating temperature range is -40°~125°. All ESP8266s act as MQTT clients and an online server acts as an MQTT broker. Along with the status and energy consumption of individual devices, temperature and humidity status of the laboratory can also be monitored using sensors and viewed in mobile application.
