Overview - RTU Stations Maintenance at Daerah Timur Laut, Perbadanan Bekalan Air Pulau Pinang (PBA)

The scope of works encompassed comprehensive functionality tests and inspections on various equipment including RTU, I/O module, HART converters, with necessary RTU program modifications and updates, all documented in detailed reports. Additionally, functionality, data communication, signal strength tests, and inspections were carried out on GPRS modems, WIFI Modules, and Ethernet cable communication continuity. The project also involved meticulous inspections of the 24Vdc power supply, UPS, ELCB autoreclosure, 240Vac SPD, and 24Vdc SPD.

Lora Wireless Technology Soil Sensors

Long Range of soil sensors

The plot of land for this pilot project is about 2-3 acres in size. MARDI wanted the soil sensors to be mobilised flexibly for their R&D purposes. We have proposed and implemented LORA wireless technology which has a range of 2-5km (open area) and can be connected to at least 100 more sensors.

Movability and Flexibility of soil sensors

The soil sensors can now be moved around anywhere around the land anytime without the need to modify the infrastructure.

Ultra-Low power

The ultra-low powered lora module enables the battery powered lora FL407 to have a battery life of 3-5 years.

IOT Panel


Siemens PLC S7-1200 together with IO modules is used to collect wired signals including pump status, actuator valves status and tank water level status.

IOT gateway

Faraday Instrument’s IOT gateway is used to convert the signals from PLC and LoraWAN to the google firebase cloud.
