Title: Sensor Module for Smart Pot System
Inventor: CHOI JAE HO
IPC: G01N27/12
Filed: 2020-04-11
Abstract: The present invention provides a sensor module for a smart flowerpot system. According to the present invention, the sensor module comprises a solar cell, a lithium polymer battery, a charging board, a voltage sensor, an electrical conductivity sensor, a moisture sensor, a main processor, a Zigbee communication module, a main switch, an LED indicator, and a housing. When the sensor module is inserted into the soil of a flowerpot for culturing plants to allow the electrical conductivity sensor and the moisture sensor to be submerged in the soil and the main switch is turned on, a voltage of the lithium polymer battery is detected from the voltage sensor every set time so that the amount of voltage fluctuation and a detection time are calculated to be converted into the amount of sunlight received by the plant, the electrical conductivity in the soil is detected from the electrical conductivity sensor to be converted into the amount of nutrients in the soil, and the amount of moisture in the soil is detected from the moisture sensor, so that the amount of sunlight, nutrients, and moisture are transmitted to a sensor server through the Zigbee communication module. The sensor server transmits the information to a web server and a user accesses the web server with a smartphone and receives the information to understand a plant growth environment and move the position of the flowerpot to increase or decrease the amount of sunlight or supply water and nutrients necessary for plant growth. Accordingly, the present invention provides an effect of helping plants to grow well.
Patent KR-20210126861-A (KR)
Inventor: JI YOUNG HYOK
IPC: H01H50/30
Filed: 2020-04-13
Abstract: The present invention relates to an electromagnetic contactor with an anti-release function, which is able to fundamentally prevent the release of a main contact point while being excited. When a current is applied to an excitation coil built in a body unit, an electromagnet becomes magnetized, and an operation contact point is pulled toward and comes in contact with a fixed contact point, thereby closing the main contact point. When the magnetization of the electromagnet is released, the main contact point is opened. The electromagnetic contactor with the anti-release function comprises: an operational state detection unit having an engagement block which is detachably engaged with one side of the body unit and elevated by being linked to the operation contact point; a release flow sensing unit including a release flow detection terminal fixed in the operational state detection unit, and an operation terminal for release flow detection installed in the engagement block to face the release flow detection terminal; a release flow determination unit connected to the release flow detection terminal and determining that a release flow has occurred to the main contact point when the operation terminal for release flow detection is detached from the release flow detection terminal; and an release prohibition command generation unit which, when the release flow determination unit determines that there is a release flow of the main contact point while a current is being supplied to the excitation coil, generates a release prohibition command for strengthening the magnetism of the electromagnet. In accordance with the present invention, the release flow sensing unit of the operation status detection unit is released before the main contact point, so the release flow of the main contact point can be recognized in advance. In addition, the release prohibition command for strengthening the magnetism of the electromagnet is generated when the release flow is detected, so the release of the main contact point from the excited state can be fundamentally prevented.
