With the rapid development of Industry 4.0 and IoT, more and more wireless related products have been developed. This study develops a Modbus-based Wi-Fi router with a built-in Wi-Fi module for data collection from multiple devices via RS-485. This Modbus-based wireless router can receive temperature, humidity, CO, CO2 data from sensors through RS-485. The readings are available from local or remote displays. The HMI (Human Machine Interface) display can be configured by users for Industry 4.0 related applications. It does not only simplify wired connection, but also achieves an implementation of IoT concept.
