The paper describes the development of a Wireless Sensor Network for Temperature and Humidity Monitoring System. The prototype is based on NodeMCU ESP8266 module that automatically record the current parameters and allowing the user to interact with the monitoring system wirelessly. A total of three wireless microcontrollers are used as sensor nodes and actuator node to form a wireless sensor network. Each node is connecting to online cloud storage that helps to receive, process and send the information to and from the desired nodes. The data communication from the wireless sensor nodes to the cloud database is done via MATLAB ThingSpeak. Within the monitoring system facility, the access network is based on ESP8266 Wi-Fi network, which are enabling the concept of Internet of Things. The monitoring system is deployed to the room exhaust ventilation system (REVS) which include 3G technology in it allowed the stand-alone REVS system monitoring remotely via web or mobile application at low cost. Experimental results show that the system is capable to use a unified approach to recording, displaying and controlling the temperature and humidity parameters through several IoT platforms: MATLAB ThingSpeak, ThingView App and REVS mobile application developed using MIT App inventor.
