This paper presents a double-radio node for RF transmission, designed to provide a transparent transmission module for 433MHz wireless sensor network. It is a pure node without any sensors, exchanging message with other machines through serial port. A double radio configuration enhanced the communication quality. We desired to make the node as a universal, portable RF transmission module which can be simply applied to wireless sensor network. Customers can use the double radio both as receiving, both as sending, or one for each transmission mode. Experiments show a nice communication stability and range of this node.
