The invention discloses a grain moisture condensation detection system based on microwave technique, relating a grain storage detection technique, comprising an antenna assembly, a control circuit, and an upper computer processing system, wherein, the antenna assembly transmits microwaves below to the grain surface and receives microwaves, the control circuit provides power supply and pulse signals required by the system and digital processing and transmitting the received signals, and the upper computer processing system receives data from the control circuit and displays the detection results at real time. The system can be used for detecting moisture condensing zone inside the grain stored in the grain bin, can be applied in daily detection of grain storage, can timely discover moisture condensation and avoid grain loss, and has important meaning to safe storage of grain.
