1 to 3, the network touch switch using the humidity sensor according to the present invention,

It largely consists of a switch body 10 , a humidity sensor 20 , an outdoor air inlet 30 , an LED 40 , and a microcomputer 50 .

Looking at each configuration,

The switch body 10 is

As shown in Figure 1,

It is connected to the luminaire 1 through the wiring embedded in the wall so that the luminaire 1 blinks by an on-off operation by touch,

The touch area 11 is disposed in the center of the front surface, and the touch area 11 has an internal circuit that detects heat, and a detection signal through this is transmitted to the microcomputer 50, and also the touch area 11 ) is preferably a material that can transmit light.

As a result, when the touch area 11 is touched once, the LED 40 is turned on or off by the control of the microcomputer 50 .

The humidity sensor 20 is

As shown in Figure 1,

Built in the switch body (10), in particular to be mounted on the PCB board (80) provided in the switch body (10),

It utilizes the property that the resistance value and dielectric constant of organic polymers or ceramics change due to water vapor in the atmosphere. It is a sensor that electrically detects humidity by increasing the electrical resistance between electrodes.

The outdoor air inlet 30 is

As shown in Figures 1 and 3,

To be formed in an area corresponding to the humidity sensor 20 in the switch body 10,

It consists of a plurality of holes penetrating back and forth through the switch body (10).

At this time, each hole is the same diameter, and it is preferable that it is about 1-3 mm in diameter.

As a result, air in the atmosphere including water vapor is introduced through the outdoor air inlet 30 , so that it can be sensed by the humidity sensor 20 .

The LED (LED) 40 is

As shown in Figures 1 and 3,

It is disposed on the touch area 11 of the switch body 10 and is disposed on the rear side of the touch area 11 of the switch body 10 in the state mounted on the PCB 80 in particular, so that the light fixture 1 blinks. to indicate the status,

In particular, it consists of an RGB conversion type LED (LED: Light-Emitting Diode) that is converted to red, green, and blue.

The microcomputer 50 is

As shown in Figure 2,

It is for controlling the LED 40 by receiving the sensing value of the humidity sensor 20,

As a chip containing a kind of central processing unit, it is mounted on the PCB 80 .

The microcomputer 50 converts the color of the LED 40 to a color corresponding to a preset humidity range value according to the sensing value of the humidity sensor 20 .

For example, when the preset humidity range value is 40 to 70%, the LED 40 emits green light by the microcomputer 50, and when the preset humidity range value is less than 40%, the microcomputer 50 The LED 40 emits blue light, and when the preset humidity range value exceeds 70%, the LED 40 may emit red light by the microcomputer 50 .

And the LED 40 emits light when the lighting fixture 1 blinks, but the brightness is weaker when the light is turned off than when turned on by the microcomputer 50, and the color change is made in this brightness state. In other words, when the luminaire 1 is turned on, switching to red, green, and blue is made while maintaining the state in which light is emitted brighter than when the luminaire 1 is turned off. The transition to red, green, and blue is made while maintaining

As a result, the user can visually check the humidity state of the space in which the switch body 10 is provided regardless of whether the light fixture 1 is turned on or off.

On the other hand, the network touch switch using the humidity sensor according to the present invention further includes a speaker 60 and a human body detection sensor 70,

The speaker 60 is

As shown in Figure 2,

Built in the switch body (10) to be mounted on the PCB board (80),

At this time, the microcomputer 50 controls the speaker 60 so that the sound corresponding to the preset humidity range value is repeatedly generated in units of time according to the sensing value of the humidity sensor 20 .

For example, when the preset humidity range value is 40 to 70%, a beep sound, a bird sound, a brook sound, etc. at regular intervals are generated from the speaker 60 by the microcomputer 50, and the preset humidity range When the value is less than 40%, a beep sound, dry firewood burning sound, wind sound, etc. at different intervals are generated from the speaker 60 by the microcomputer 50. When the preset humidity range value exceeds 70%, the It can be implemented to generate another beep sound or wave sound at a predetermined interval from the speaker 60 by the microcomputer 50 .

This implementation is only an example and may be variously modified within a range in which a user can recognize a humidity state by distinguishing a sound according to a preset humidity range value.

The human body detection sensor 70 is

As shown in Figure 2,

Built in the switch body (10) to be mounted on the PCB board (80),

It consists of a normal infrared human body detection sensor that senses the infrared rays emitted from the human body and determines whether there is movement (motion).

At this time, the microcomputer 50 operates the speaker 60 when the human body detection sensor 70 does not receive the sensing value for detecting the human body at a preset time interval or when the light fixture 1 is turned off. will stop

As a result, when the movement of a person is not detected in the space provided in the switch body 10 for a certain period of time, the operation of the speaker 60 is stopped, and even when the light fixture 1 is turned off, the speaker 60 ), it can be implemented so that power consumption is cut off and lifespan is not disturbed by stopping the operation.

On the other hand, in the network touch switch using the humidity sensor according to the present invention

(3) interlocking control is possible.

At this time, the humidity control device 3 is composed of an ioT type humidifier and dehumidifier.

After all, according to the sensing value of the humidity sensor 20, the operation of the humidity control device 3 through the wall pad 2 can be turned on or off, and when the operation is on It can also be controlled so that it can be operated for a set time or for a reserved time.

On the other hand, in the network touch switch using the humidity sensor according to the present invention

As shown in FIG. 3, the humidity sensor 20, the LED 40, the microcomputer 50, the speaker 60, and the PCB board 80 on which the human body detection sensor 70 is mounted has a guard for protecting it from external temperature. A layer 81 is formed.

At this time, the guard layer 81 is formed using a coating solution containing a silicone resin and glass fiber, and preferably has a thickness of 20 to 50㎛.

The PCB substrate 80 is exposed to various temperature conditions, and the humidity value measured by the humidity sensor 20 and the humidity sensor as it is also exposed to indoor temperature and heat generated by components such as the LED 40 . The guard layer 81 is further formed to compensate for the humidity values in the corners, etc., in the same space far away from (20).

The guard layer 81 is formed using a coating solution containing a silicone resin and preferably has a thickness of 20 to 50 μm. If the thickness of the guard layer 81 is too thin, it is difficult to protect the parts against impact. It was found that performance degradation due to impact occurs, and if the thickness is too thick, the size of the device becomes too large and the guard layer 81 is easily peeled off.

Specifically, it is preferable to use a coating solution containing glass fibers together with a silicone resin so as to protect the PCB 80 at a low temperature as the coating solution. In particular, it was found that the silicone resin and the glass fiber are preferably mixed in a weight ratio of 6:4 to 7:3.

The glass fiber is excellent in electrical insulation and incombustibility, and has a low coefficient of thermal expansion, so dimensional deformation according to temperature and humidity is small. Therefore, when the content of the glass fiber is too large, the coating performance is deteriorated, so that it is difficult to form the guard layer 81, and when the content of the glass fiber is too small, the performance at low temperature is reduced.

Therefore, it is greatly helpful in allowing the humidity sensor 20 to measure a more accurate humidity value for an indoor space through the thermal blocking effect of the guard layer 81 .
