Automatic flower watering device based on capacitive sensing principle

Abstract

The invention relates to the technical field of Internet of things, and discloses an automatic flower watering device based on a capacitive sensing principle. The automatic flower watering device comprises a framework, wherein a culture vessel is fixedly arranged at the bottom end of the inside of the framework; water containing vessels are respectively and fixedly arranged at the left end and theright end of the bottom of the culture vessel; an extrusion rod is glidingly connected inside each water containing vessel; the lower end of the water containing vessel is fixedly provided with electrode plates; and electrode media are movably arranged inside the electrode plates through reset springs. The automatic flower watering device has the advantages that water in the water containing vessels is absorbed through plant soil; the water can be continuously reduced; in the reduction process, under the effect of the elasticity of the reset springs, the electrode media are driven to upwardsmove; according to a capacitor principle, the area of the electrode media right aligned with the electrode plates is reduced, and the current passing through capacitor plates is reduced; after receiving a current reducing signal, a driving device drives a screw rod to rotate, and watering can be performed on plants in the culture vessel; and the automatic watering effect is achieved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to an automatic watering device for flowers based on the principle of capacitive sensing. Background technique [0002] The Internet of Things refers to the network engineering that collects any objects or processes that need to be monitored, connected, and interacted in real time through various devices and technologies such as information sensors and sensors, and collects the data we need to achieve the desired goal. Let all ordinary physical objects that can be independently addressed form an Internet interoperable network. [0003] The existing family planting flowers, in the usual planting process, often causes the flowers to wither or even die due to untimely watering, which brings certain troubles to the people who plant flowers, and if they need to travel far away at ordinary times, there is no need to Taking care of flowers has always been a difficult proble...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic watering device for flowers based on the principle of capacitive sensing, which has the advantages of being able to automatically sense whether the flowers need a water source, and realize automatic spraying of the water source for the flowers, etc., which solves the problems in the existing devices. Unable to sense whether the flowers need water, only regular watering
