The utility model discloses a solution density detection device based on a pneumatic sensor, relates to the field of solution density detection, and solves the problem that a conventional density detection device is complex in structure and inconvenient to carry. The solution density detection device adopts the structure that a container with scales is used for being filled with a solution to be detected; the tail end of a circular tube with scales is sleeved with a probe of the pneumatic sensor in a sealing manner; a pneumatic detection circuit is used for detecting air pressure outside the solution to be detected or detecting air pressure inside the circular tube with the scales; a signal output end of the pneumatic detection circuit is connected to a signal input end of a singlechip control circuit; a solution density display signal output end of the singlechip control circuit is connected to a display signal input end of a liquid crystal display circuit; a keyboard input circuit is used for inputting a so
