Environmental monitoring system based on LoRa is a combination of hardware and software that creates a dedicated computer system that is able to sense environmental parameters using designated sensors, processed the value by microcontroller and transmit the acquired data to the LoRa receiver and store it in the cloud. All data can be viewed real-time within 10 minutes interval at the website as stated above.

The project was conducted at University Malaysia Terengganu (UMT) research station (Stesen Penyelidikan Alami Marin) in Bidong Island, Terengganu. The transmitter node was placed on hilltop of Bidong Island fixed with 6 meter height of communication tower while the receiver node located on the roottop of Central Lectures Complex (Kompleks Kuliah Pusat) in UMT Campus, Mengabang Telipot. The communication range between transmitter and receiver is around 23km from each other with Line of-Sight radio link.

An environmental monitoring system is one of the important system to monitor the changes in climate continuously such as the changes in ambient temperature, relative humidity, barometric pressure and barometric altitude. This environmental monitoring system provides all the real-time data and effectively used in remote monitoring purposes from Bidong Island to UMT campus with the distance at 23km. The result is useful to monitor the environmental changes and at the same time can be used as an emergency disaster management in the future.
