Continuous data monitoring of various type of Geotechnical Instruments - Rain Gauge, Strain Gauge, Piezometer and In-placed Inclinometer were made possible, with threshold exceedance at sites trigger alert by sending text mssages to cell phone and email.


The first project of this Telemetry Wireless Internet Monitoring System with three level threshold of rain fall intensity, has been implemeted at the Bukit Lanjan site. The second project was implemented at Shah Alam site which include the monitoring of movement with MEM Chip In-placed Inclinometer and water level with Piezometer. The third project has been implemented at Genting Highland with three Rain Gauges and ten Tiltmeters installed at different location at hillside.
