WS433-R (old name is WR433) is a wireless co-ordinator in a wireless sensor network. It is able to configure the parameters for all end nodes in the network. By the Sub-Ghz technology from Texas Instruments, it is easy to establish multiple networks in same area without interference or channel conflict. One co-ordinator can handle maximum of 40 end nodes in its network.
