IoT Modules

USR IOT's IoT modules can realize the transmission and reception of wireless data between things, link the perception layer and the network layer of the Internet of Things, and improve efficiency by managing data.

Due to different data transmission requirements in various industries, communication modules are widely classified. Users can choose the embedded IoT modules according to their own needs to achieve wireless data transmission.
