TREE-TILT SENSOR TECHNOLOGY IMPLEMENTED IN SENTOSA
About 100 of our wireless sensors will be installed on important and prominent trees to monitor them and detect early when they start to lean and possibly fall to prevent accidents from occuring on the island. This early detection allows preventative measures to be taken such as improving soil conditions and pruning tree crowns. Monitoring trees that are most likely to cause problems if they were to fall on busy areas with human traffic are invaluable to preventing accidents in those areas. In 2017, a 38-year-old woman was killed when a 40m tall heritage tree toppled on her while she was attending a public concert at the Singapore Botanic Gardens.
It is essential to monitor tree behaviour especially during strong wind and heavy rain conditions as it can be hard to tell when a tree might topple, even unlikely ones. Manual inspection of trees can be supported by live data from the sensors to increase risk mitigation and intervention measures. NParks plans to eventually install more sensors on a larger scale of trees around Singapore as the Republic experiences heavier rainfall.
