“IoT Smart Gateway for Bluetooth Electronic Meters” Wins First Prize
At KMUTNB’s 2025 Invention and Innovation Contest
The Sirindhorn International Thai-German Graduate School of Engineering (TGGS), King Mongkut’s University of Technology North Bangkok (KMUTNB), proudly congratulates its research team for winning the First Prize at the 2025 KMUTNB Invention and Innovation Contest for their project:
“IoT Smart Gateway for Bluetooth Electronic Meters.”
The project was led by
Assoc. Prof. Dr. Chaiyot Pirak,
In collaboration with Dr. Nattanun Tangsunantham, Mr. Somchai Thepphaeng, Mr. Thanayut Saengsuwan, and Mr. Waranyoo Nontabut.
About the Innovation
As Thailand continues to advance toward a Smart Grid infrastructure, utility authorities such as the Provincial Electricity Authority (PEA) and the Metropolitan Electricity Authority (MEA) are transitioning from analog meters to smart meters. However, due to the high cost of smart meters, lower-cost Bluetooth-enabled electronic meters have been considered as an alternative, despite their limitations in cloud connectivity.
This award-winning innovation addresses the gap by introducing an IoT Smart Gateway that can simultaneously read data from groups of Bluetooth meters (at least 20 devices per gateway) and transmit the data to cloud-based IoT platforms via NB-IoT, CAT-M1, or 3G/4G networks.
The system also includes a Plug&Play communication modem with modular support, allowing remote configuration via IoT systems or local setup through a mobile app. Most importantly, the gateway is designed to be compatible with a wide range of electronic meter brands available in the market.
This innovation is a remarkable example of TGGS’s commitment to practical engineering solutions that meet industrial demands and support national infrastructure development.
