Abstract: The usage of sensors to monitor water quality at Lake Chini started in 2010. Its purpose is to facilitate authorities in controlling the source of pollution and indirectly monitor and enforce the rules set out under the water enactment act. Water quality Index is used to measure cleanliness and the quality of water to sustain the rich and diverse biodiversity of flora and fauna. The telemetry system in operation since 2010 is adequate for such purpose. However, the rampant logging, mining and plantation activities in the last 5 years discharged waste such as sediment, fertilizer and toxic into the lake and threaten the lake biodiversity. The sensors operated within a polluted environment. The big flood of 2014/2015 further decimated all telemetry stations and rendered them inoperable. We are faced with the challenge of rebuilding the collapsed infrastructure and resuming the measurement of water quality parameters. The new telemetry system incorporated two new features to ensure accessibility: A dashboard and early warning system and moving data and application into the cloud. A smartphone app was developed to facilitate the acquire readings from sensor and facilitate the sharing of these data.
