Because of its portability, the non-cable seismograph has become the future development trend of geophysical instruments. A new wireless data transmission device of 433 M module was proposed; a wireless network was built using the EL1663B_PA module of the SI4463 core, and through the SPI interface to modify the internal parameters. Data transmission used dual antenna mode, the main station as the center of the wireless network coverage up to 550 m or more. The wireless time synchronization system was designed to realize the wireless connection communication between the shallow seismograph and the sensor of each observation point. This program aimed to eliminate the necessary connecting cable and batteries between the conventional shallow seismograph and the detector, greatly reducing the weight of the equipment, and making the shallow seismograph truly low cost, lightweight, flexible and easy to operate and so on.
