Digital pressure sensor

The invention discloses a digital pressure sensor, and particularly relates to the technical field of pressure sensors, the digital pressure sensor comprises a shell, a sensor body is arranged in the shell, a probe is arranged at the top end of the shell, and a ventilation assembly for cooling and heat dissipation is arranged outside the sensor body; the bottom end of the shell is provided with a buffering assembly used for buffering impact. The ventilation assembly comprises an air inlet pipe, a draught fan is arranged in the air inlet pipe, and a plurality of air pipes are arranged at the rear end of the draught fan. External cold air is conveyed into the air pipe through operation of the draught fan, meanwhile, the multiple driven gears meshed with the main gear are driven to rotate, and therefore the spiral row can be driven to stir water in the water pipe to flow, the heat dissipation performance can be improved through air circulation and water circulation, the air circulation is located in the air pipe
