Miniature GPS tracker board, using GSM for data transmission, Bluetooth for communication with a phone, accelerometer for theft detection, memory storage, battery management system, interface for e-bike systems. It fits inside the bike tube and uses external antennas.

Vibration acquisition network

Construction of a network of 3D vibration sensors that can be used in a variety of environments, including spread around a car to record vibrations. A custom communication protocol was implemented for high speed communication, synchronization and data acquisition. All the measurements are collected through USB to a larger embedded system where the signal processing takes place.

GPS tracking system via GSM

GPS tracker system, using GSM for data transmission and storage to the cloud. It also features SD-card storage, bluetooth and external antennas. The interface is an Android application used for online and offline tracking of the device.

Security network composed of compact devices

Network composed of multiple autonomous, compact surveillance devices. Devices are equipped with video camera, infrared detector, storage, passive PoE, Ethernet communication with peers. Each device works autonomously, doing image processing and motion detection inside the chip, auto rotates to the area of interest, stores video feed both on the board storage and on the server and communicates with its peers about detections and alarms. The layout of the network and manual monitoring is done from a centralized GUI.
