LPKIT – Low Power IoT Sensor and Gateway System is an integrated communication system developed by Demsay for industrial IoT, defence electronics, remote monitoring, and field data acquisition applications. The system consists of a low-power sensor node and a central gateway unit.

The LPKIT-Sensor collects environmental and operational data, including temperature, humidity, motion, presence, and vibration. Its integrated three-axis accelerometer supports motion and vibration analysis, while the MAX17048G+ battery monitoring circuit enables precise energy tracking. The onboard NFC/RFID infrastructure also supports contactless identification and asset management applications. Its low-power architecture is designed to support efficient operation in long-term field deployments.

Collected data is transmitted to the LPKIT-Gateway through the LoRa E5 communication module, providing long-range and low-power wireless connectivity. Built around an ESP32-S3 architecture, the gateway establishes a reliable communication infrastructure between distributed sensor nodes and central monitoring systems. A DWIN smart display and UART interface support real-time data visualization and system control, while Micro SD card support enables local data logging. The USB Type-C interface provides power supply and high-speed data transfer.

The modular architecture of the sensor and gateway units can be expanded according to different field requirements, enabling multiple monitoring points to be centrally managed and evaluated through a unified platform.

LPKIT provides a scalable infrastructure for facility and warehouse monitoring, environmental condition tracking, field equipment status monitoring, vibration analysis, remote telemetry, inventory and asset tracking, maintenance operations, industrial automation, and defence electronics development.
