This RF Communication module enables remote operation of sensors or sensor chains without requiring Bluetooth or Wi-Fi in the connected PC. The system consists of two RF modules — one connects to a remote sensor or chain (powered by a Battery Module), and the other connects to a Monitor Display Unit or PC via a USB module. Multiple RF units can be used simultaneously to accommodate multiple sensor chains. The system operates at 2.4 GHz DSSS (Direct-sequence spread spectrum) with a bit rate of 1 Mbps and a maximum open-space range of 30 meters. Two RF units are included in this package.
