Abstract

The invention discloses a device for automatically monitoring and controlling humidity in a greenhouse for greenhouse cultivation, which comprises an electrothermal humidifier, a transformer, a humidity sensing sensor, a first resistor to an eighth resistor, a first not gate to a fourth not gate, a first capacitor to a fourth capacitor, a first relay, a second relay, a first triode, a second triode, a rectifier, a three-terminal voltage regulator, a voltage regulator, and a diode. According to the device for automatically monitoring and controlling humidity in the greenhouse for greenhouse cultivation, the humidifier can be automatically started for humidification when humidity in the greenhouse is over low, tedious manual management can be avoided, the working efficiency is improved, and popularization is facilitated.

Description

technical field [0001] The invention relates to a humidity controller, in particular to an automatic monitoring and control device for humidity in a greenhouse for planting in a greenhouse. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation properties. Its appearance allows people to eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. And will guarantee for the humidity in the greenhouse, in the prior art mostly is to often check by manually, and the work is heavy, and the labor load is big. Contents of the invention [0003] The object of the present invention is to provide an automatic m...
