Real Time Infrared Distance Sensor for Cyber Physical Systems Using Arduino-LabVIEW Integration

This study presents a real-time IR distance sensing system for cyber-physical systems (CPS) applications, integrating Arduino hardware control with LabVIEW analytics. The system employs an infrared emitter-photodiode array for non-contact detection within a 0–25 cm range, using the inverse square law for precise measurements and obstacle detection. A digital filter reduces noise by 40 dB, and a hybrid calibration method, linear interpolation and quadratic regression, mitigates voltage-distance nonlinearities. Real-time data acquisition via Arduino and networked signal processing in LabVIEW ensure sub-200 ms latency. Experimental validation in dynamic environments confirms its efficacy in robotics and industrial automation, offering a scalable, low-cost solution for enhancing situational awareness in distributed CPS deployments.
