The invention provides a gravity induction counter system. The system comprises a counter, goods grids, gravity inductors, a wireless transmission module and a remote server; each counter comprises multiple goods grids, and each goods grid accommodates the same type of goods; the gravity inductors are arranged in the bottoms of the goods grids respectively, and used to detect the weights of the goods on the grids; the wireless transmission module sends weight information of the gravity inductors to the server; and according to the weight information, the remote server calculates the amount of goods on the grids and sends an out-of-stock prompt. According to the system, weight change of the goods in each goods grid can be monitored in real time, information including sales information of the goods and popular information of the goods grids can be obtained according to the weight change, purchasing behaviors of the consumers can be analyzed according to the information, and basis is provided for goods arrangement.
