Description

Application of Internet of Things in humidity monitoring system for automatic watering

The invention provides a soil moisture monitoring system, in particular to a humidity monitoring system using the Internet of Things in automatic watering.

In general, there are many aspects that need to be paid attention to when planting plants, such as humidity, temperature, soil pH, etc. Any variable will affect the growth of the plant. Therefore, proper monitoring of temperature, humidity, and pH values will produce high quality. The necessary prerequisites for crops. However, the average farmer cannot effectively monitor due to economic considerations and personnel restrictions. Therefore, a humidity monitoring system for automatic watering that can achieve automatic effects is needed.

In addition, generally in the process of planting crops, different crops will have different characteristics, and the requirements for soil moisture are also different. For example, plants with longer roots have higher requirements for deep soil moisture, and conversely, shallow root plants There is no such requirement. In addition, the average user cannot observe the moisture state in the depth of the soil through the naked eye during the irrigation process, so a monitoring system capable of accurately controlling the humidity is needed.

The invention provides a humidity monitoring system applying the Internet of Things to automatic watering. The main purpose of the invention is to provide an automatic and accurate humidity monitoring system.

To achieve the aforementioned objectives, the present invention applies the Internet of Things to the automatic watering humidity monitoring system, including:

A plurality of humidity monitors are provided in the soil at different depths, each of the humidity monitors is used to monitor the soil humidity at different depths, each humidity monitor outputs the detected humidity as an electronic signal, the electronic The number of signals is the same as that of the monitor;

An Internet of things module circuit with a signal connection of a preset module, a comparison module, and an output module, the preset module is connected to the signals of the humidity monitors, the preset module has a plurality of valves Value, each electronic signal is compared with the threshold to output a digital signal, when the electronic signal is greater than the threshold, the digital signal output is 1, when the electronic signal is less than the threshold, then The digital signal is 0, and there is a preset table in the comparison module, the preset table implies the relationship between each digital signal and a control signal;

A sprinkling control valve is connected to the signal of the output module, and the sprinkling control valve is used to receive the control signal and open or close according to the control signal.

As can be seen from the foregoing, the present invention is mainly by setting a plurality of humidity monitors in the soil at different depths, and thus can comprehensively judge the overall state of the soil, and make a more accurate judgment on whether to sprinkle water. At the same time, through the Internet of things module circuit ratio For the preset table, the control signal is obtained to automatically control the sprinkling control valve to open or close, so as to achieve the purpose of automation and precise control of humidity.

The present invention provides a humidity monitoring system that applies the Internet of Things to automatic watering. Please refer to Figures 1 and 2, including:

A plurality of humidity monitors 10, each of the humidity monitors 10 is arranged in the soil of different depths, each of the humidity monitors 10 is used to monitor the soil humidity of different depths, and the detected humidity is in the form of an electronic signal S Output, the number of electronic signals S is the same as the number of the monitor 10, the electronic signals S can be a voltage value;

An Internet of things module circuit 20 has a signal connection of a preset module 21, a comparison module 22, and an output module 23, the preset module 21 is signal-connected to the humidity monitors 10, the pre- Assume that the module 21 has a complex threshold, and each of the electronic signals S is compared with the threshold to output a digital signal. When the electronic signal S is greater than the threshold, the output digital signal is 1, when the When the electronic signal S is less than the threshold value, the output digital signal is 0, and the comparison module 22 has a preset table that implies the relationship between each digital signal and a control signal. In this case, the preset table records the relationship between the arrangement and combination of the digital signals and the control signal. For example, the number of humidity monitors 10 is five, and the humidity monitors 10 are defined as a first humidity monitor 11, a second humidity monitor 12, a third humidity monitor 13, a fourth humidity monitor 14, and a fifth humidity monitor 15, each of the digital signals of the humidity monitor 10 is a first digital Signal, a second digital signal, a third digital signal, a fourth digital signal, a fifth digital signal;

The preset table uses the first digital signal, the second digital signal, the third digital signal, the fourth digital signal, and the fifth digital signal as the default conditions, and corresponds to the state of the control signal, as shown in Table 1, For example, when the first digital signal, the second digital signal, the third digital signal, the fourth digital signal, and the fifth digital signal are all 1, the output control signal is state 1, when the first digital signal, the first When the two-digit signal, the third-digit signal, the fourth-digit signal, and the fifth-digit signal are all 0, the output control signal is state 0. Situation 1 2 3 4 5 6 First digital signal 0 1 1 1 1 1 Second digital signal 0 0 1 1 1 1 Third digital signal 0 0 0 1 1 1 Fourth digital signal 0 0 0 0 1 1 Fifth digital signal 0 0 0 0 0 1 Control signal 0 0 0 0 0 1 Table 1

A sprinkling control valve 30 is connected to the output module 23 signal of the IoT module circuit 20. The sprinkling control valve 30 is used to receive the control signal and open or close according to the control signal. When the control signal is in the state 0, the sprinkling control valve 30 is closed. On the contrary, when the control signal is in the state 1, the sprinkling control valve 30 is opened, so that it can decide whether to sprinkle water.

Preferably, please refer to FIG. 3, the IoT module circuit 20 further has a wireless communication unit 24, the wireless communication unit 24 is signal-connected to the comparison module 22, the wireless communication unit 24 may be WIFI, etc. The wireless communication unit 24 is wirelessly connected to a mobile device E, so that the user can instantly observe the soil humidity and the watering condition.

As can be seen from the foregoing, the present invention is mainly provided by setting a plurality of humidity monitors 10 in the soil at different depths, which can comprehensively determine the overall state of the soil and make a more accurate judgment on whether to sprinkle water, and at the same time through the IoT module circuit To compare the preset table, obtain the control signal to automatically control the sprinkling control valve 30 to open or close, so as to achieve the purpose of automation and precise control of humidity.
