Abstract: One of the primary challenges when integrating PLCs with IoT or remote monitoring systems is ensuring compatibility between the PLC’s I/O interfaces and the Wi-Fi module. This project presents a low-cost module utilizing the ESP8266 Wi-Fi module and ULN2003 driver to remotely control and monitor programmable logic controllers (PLCs) via Wi-Fi. The growing demand for affordable and efficient automation systems in industries, especially among small and medium-sized enterprises, has driven the need for wireless solutions. By integrating the ESP8266’s wireless communication capabilities and the ULN2003’s high-current load interfacing, the system provides a cost-effective alternative to traditional wired methods. This wireless module simplifies installation, reduces maintenance costs, and offers real-time control and monitoring via a user-friendly web interface accessible from any internet-enabled device. The proposed solution aligns with Industry 4.0 trends, enhancing operational efficiency and flexibility.
