Abstract
Currently, the department of Jabatan Kerja Raya (JKR) in Malaysia depends on the notification from public’s complaints or on-site spot checks when there are tilted road sign boards. This has caused delays in repairs and could put public safety in jeaopardy. In this paper, an IoT-based alert notification for tilted road sign boards using solar energy is proposed. A Rapid Application Development methodology (RAD) is used to produce a working prototype of the proposed system with NodeMCU ESP8266 microcontroller and Arduino IDE. The results of our implementation show that we are able to detect tilted sign boards and send email alert notifications to the responsible parties accordingly.
