▎ 摘 要
NOVELTY - The method involves connecting multi-node units to a wireless network. Radio wave of transmission data is detected by the multi-node units, where the multi-node units are joined by a network cable and provided with two removable antennas. The antennas are fixed on a fixing device. USE - Networking based graphene sensor data collecting method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of multi-node units.
