Abstract Dengue fever has become an increasingly significant health threat worldwide. Currently, due to lack of specific treatment or vaccine against dengue, vector control, which is available in many forms, remains a key strategy for dengue fever prevention. Hence, we introduce an iAMR: Intelligent Auto-Dispenser Mosquito Repellent, an innovative system in line with “Industry 4.0” concept where it includes current trend of automation and data exchange. It also includes cyber-physical systems, the Internet of things, cloud computing and cognitive computing. The iAMR solves the issues of when to spray (by auto-spray using sensor) and long live batteries (with LORAWAN technology). When combined with the mini aerosol (X’MOS), it provides an even more effective mosquito control. This all-in-one system ensures a mosquito-free environment in your home. The iAMR device relies on the microcontroller and sensor in order to operate the intended spraying task. The microcontroller used is an IoT based device called ESP8266 which is a WiFi-embedded microcontroller that utilized standard everyday WiFi band frequency which is at 2.4 GHz. A DC geared motor sensor for dispenser device is used. The main contribution of iAMR is to monitor and track for the mosquito repellant (X’MOS) to be refilled. The implementation shows the iAMR system able to update the level of each X’MOS in iAMR devices which reducing the cost of manual human checking for X’Mos refill.
