Online network monitoring of the grain storage amount in grain depots is a new technology. The layout of pressure sensor nodes is the key point in the whole monitoring system. Grain depot pressure sensor network system includes the architecture of the entire network and a sensor layout model in the depots. A system structure of the pressure sensor network special for the depots is designed according to the depot distribution characteristics, and a sensor layout model based on region segmentation is presented according to the grain characteristics in the storehouse. In comparison with several models in literatures, the sensor node layout is optimized by the method. Test showed that the pressure sensor layout model has good performance.
