This project is intended to provide a solution to a company's problem of developing a smart motion detection device for home and office security applications. The company intends to deploy 100s of these motion detectors throughout the Greater London Area. As a result, each motion detector will require a low power wide area network (LPWAN) wireless interface. Unlike traditional motion detectors, which detect only motion, the proposed motion detector will be able to detect motion direction (e.g., whether a person is leaving or entering a room) by analyzing signals from multiple motion sensors. The basic idea is that if three motion sensors are placed along the corridor: Sensor 1 - Sensor 2 - Sensor 3, the sequence of sensor activations will provide information about the direction. The first section 1.0 of this report covers the project’s general introduction. Section 2.0 provides description of Low Power Wide Area Network technologies (LoRA, SigFox, NB-IoT), including the operating principle, characteristics, hardware, and recommendation for the most appropriate technology. Section 3 describes how to write code for the Raspberry PI to analyse signals from a 4x4 PIR array to detect motion direction (left, right, up, down) and display the results on an LCD screen. The final section discusses the conclusion future work and recommendations.

Keywords: LPWAN, Raspberry PI, motion direction, smart motion detection device, PIR array
