Abstract

Provided are a barometric liquid level gauge, a liquid storage device, and a plant protection device, including: a barometric sensor, a first waterproof tube communicating with the barometric sensor, and a vent tube whose inner tube diameter is greater than the inner tube diameter of the first waterproof tube. One end of the vent tube communicates with the barometric sensor through the first waterproof tube, and the other end is configured to extend into liquid to sense water pressure. Under normal conditions, the first waterproof tube can communicate with the vent tube and the barometric sensor, enabling the barometric sensor to normally sense the pressure in the vent tube and achieve the liquid level detection function. In addition, the first waterproof tube can also provide waterproofing for the barometric sensor.
