mmWave Presence and Occupancy Sensor
24GHz FMCW millimeter-wave radar sensor detecting micro-movements, breathing, and static human occupancy.
Project Overview
Unlike passive infrared (PIR) motion sensors, this mmWave radar node penetrates non-metallic obstacles and senses stationary human presence via chest micro-vibrations for intelligent HVAC and lighting control. ### Practical Student Engineering Solution Fully functional hardware demonstration prototype equipped with dedicated microcontrollers, precision sensors, actuators, and an interactive cloud/mobile telemetry dashboard. ### Key Learning Outcomes - Embedded C / MicroPython firmware architecture and sensor interfacing - IoT telemetry protocols (MQTT / HTTP / BLE / LoRaWAN) - Power regulation, hardware debugging, and PCB design principles - Comprehensive technical documentation aligned with IEEE academic standards
Modern commercial and industrial infrastructure requires automated, real-time sensing and telemetry. Conventional manual monitoring suffers from high latency, human error, and lack of predictive fault visibility for mmWave Presence and Occupancy Sensor.
A turnkey engineering prototype integrating high-precision sensor modules, dedicated microcontroller unit, and cloud telemetry protocols to automate measurement, trigger alert thresholds, and provide remote dashboard control.
