AsiaRF AWH575-MF1 is a Wi-Fi HaLow module designed for industrial IoT (IIoT) applications such as low-power wireless communication for large ranges. Adhering to the IEEE 802.11ah standard and operating in the sub-1 GHz band, the module facilitates reliable connections up to more than 1 km in range, thus suitable for large industrial premises and distant field monitoring systems.

It has typical industrial interfaces like RS485, RS232, I2C, and SPI in order to connect a variety of sensors, controllers, and legacy industrial devices with ease. The flexibility makes it accommodate applications in factory automation, building automation systems, and remote data acquisition schemes.

The module is optimized for low power consumption, which enables multi-year battery life in-field operation with minimal maintenance. It also allows high device density and accommodates thousands of nodes on a single network, which is required for scalable IIoT deployment in smart manufacturing facilities and other industrial environments.
