Automatic spraying system applied to greenhouse

Abstract

The invention discloses an automatic spraying system applied to a greenhouse. The system comprises a temperature and humidity sensor, a microprocessor, a reset circuit module, a crystal oscillator circuit module, a relay module and a display module, wherein the reset circuit module and the crystal oscillator circuit module are connected with a microprocessor to form a singlechip minimum system; the input end of the microprocessor is electrically connected with the temperature and humidity sensor, the output end of the microprocessor is electrically connected with the relay module and the display module, and a normally open contact in the relay module is connected in series in a water pump circuit for turning on or off a power supply; and the temperature and humidity sensor transmits collected temperature value and humidity value to the microprocessor, and the microprocessor displays the received information through the display module. The system can automatically irrigate, and has achieved better effect through practical application in small greenhouses and home gardening. When the value detected by the temperature and humidity sensor reaches the set value, the system can automatically spray water.

Description

technical field [0001] The invention relates to the field of agricultural automation, in particular to an automatic spraying system applied to a greenhouse. Background technique [0002] Crop growth in small greenhouses or flower planting in home gardening requires the detection and control of soil moisture, the most basic crop growth environment. The products in the market for this kind of demand generally use timers to water regularly. The advantages are simple control circuit, low cost and easy to use. The disadvantage is that it is impossible to reasonably supplement water according to the water demand of crops or plants, which affects their normal growth. [0003] Therefore, it is necessary to involve a system that can automatically spray according to the degree of soil dryness. Contents of the invention [0004] According to the deficiencies of the prior art, the present invention provides an automatic spraying system applied to a greenhouse. [0005] The present ...
