The aim of this research is to construct a rover for environmental condition monitoring, as an alternative for conventional monitoring system and data gathering via the use of closed-circuit TV (CCTV), personnel and detection animal. The system can be deployed to assess damage and toxicity of areas based on reading from sensors, and for monitoring through visual image from the camera. The rover employs the Internet-of-Things (IoT) concept and is able to monitor the condition of the environment via the help of sensors such as humidity sensor, temperature sensor, air quality sensor, ultrasonic sensor and also with the help of camera. The developed rover will be controlled by a mobile application as the GUI, and the data from the sensor and the camera image can be monitored through the mobile application. If obstacle is detected by the ultrasonic sensor, the mobile application will give notification towards the user through the mobile application, to warn of possible collision. The data from the sensor is sent to the MySQL database and the system is connected via Wi-Fi. The data can be accessed by the user later and can also be used to perform further analysis ifneeded. This rover is compact in size, able to enter areas that are hard to access, and its usage will lower the cost of monitoring with lower development cost of the rover.
