Communication systems, controls, control methods, and programs

Abstract

An object of the present invention is to provide a communication system, a control device, a control method, and a program that can inexpensively acquire highly reliable sensor data. A communication system according to the present invention includes a control device, a plurality of lighting devices, and an IoT device. The lighting devices output modulated light beams that are modulated, the IoT device receives each of the modulated light beams, uses information obtained from each of the modulated light beams as metadata, and transmits, to the control device, the metadata and collected sensing data in association with each other, and the control device controls generation and output of the modulated light beams to the lighting devices, estimates a position of the IoT device from the metadata, and stores the position of the IoT device and the sensing data in association with each other.
