SIRC Corporation provides IoT sensors that can be retrofitted to existing equipment without large-scale construction for factories and plants. The main products include the "IoT Power Sensor Unit," which allows for easy measurement of power consumption for each piece of equipment and can be installed in about 15 seconds, and the "IoT Angle Sensor Unit," which can convert existing analog meters into IoT devices. Additionally, SIRC has developed its own cloud service, "SIRC Cloud," to visualize this data and support centralized management of on-site data. SIRC supports "on-site DX" that can be initiated while valuing and making the most of existing equipment.
