What are the applications of humidity sensors in intelligent drip irrigation water saving system?

Intelligent drip irrigation water saving system solution for agriculture and forestry mountain, large field planting wide distribution, monitoring points, wiring power supply difficulties and other characteristics, based on the leading "Internet of Things, mobile Internet, cloud computing" technology, the use of high-precision environmental information collection equipment, irrigation water consumption intelligent decision-making, remote / automatic control of irrigation equipment and video Based on the leading "Internet of Things, mobile Internet and cloud computing" technology, we adopt high-precision environmental information collection equipment, intelligent decision on irrigation water consumption, remote/automatic control of irrigation equipment and video monitoring equipment to realize the intelligence and automation of agricultural and forestry field production.

Intelligent drip irrigation and water saving system solution composition:

The system consists of wireless intelligent gateway, drip irrigation intelligent controller, wireless collector, solar panel, various sensors (soil moisture sensor, temperature, humidity, wind speed, wind direction, rainfall, light, foliar humidity, tree diameter sensor, soil conductivity sensor), control solenoid valve, video camera, high-definition hard disk recorder, etc., as well as cloud server software and cell phone APP software.

The detailed connection schematic of system equipment is as follows.

System function:

Data collection: The system can be externally connected to weather stations, soil moisture sensors, temperature sensors, etc., to automatically collect data recorded in the system and uploaded to the cloud server.

Valve control.

1) Fixed program control: Each valve can be set independently for irrigation program without affecting each other. Irrigation time setting: Each valve can set multiple irrigation dates (such as the months or days of the week), and each irrigation date can set the opening time (set at any time within the range of 0:00-24:00, such as 05:30 open) and closing time (set at any time within the range of 0:00-24:00, such as 12:00 close).

2) Manual control: Each valve can be opened and closed temporarily and manually in the control room.

The intelligent control system can intelligently control the opening and closing of the valves in the area according to the collected soil moisture data. If the upper limit of soil humidity in the area is set to 12 and the lower limit is 7, then when the soil humidity is lower than 7, the valve will automatically open regardless of whether the irrigation program is set at this time; when the soil humidity is higher than 12, the valve will automatically close regardless of whether the irrigation program is carried out at this time.

Data monitoring: real-time monitoring of the pressure of each part of the system, the water flow rate of each valve, the opening time of each valve, the soil moisture in each area, the electricity consumption of the system, forest fires, etc., and automatically recorded into the system and uploaded to the cloud. If there is an abnormality on site to send an alarm, or through the management personnel cell phone APP push alarm information.

Video monitoring: HD wireless cameras are deployed at video monitoring points, while the monitoring room is dynamically displayed through a large screen, supporting users to remotely conduct current video viewing, as well as monitoring video playback function.

Internet of Things technology: You can remotely log into the platform through the Internet, and you can remotely view the system operation. You can view the light, air temperature and humidity, soil humidity, soil temperature and other information of each area in real time, and you can query the historical records of each collection data; you can also remotely issue control instructions to the system and prepare irrigation programs.

Information traceability: The situation of trees in the whole growing process and the surrounding environment are all recorded in the background server through the equipment, which provides a traceability basis for future analysis and research of trees by scientific research institutions or for end users who need to understand the process information.

System operation rights: Different operation rights can be set for different types of users, farm information can be added and maintained in the system independently, different equipment can be authorized for different areas, and equipment information can be managed in the system.

Intelligent drip irrigation and water saving system features

1、By adding automatic control system, the irrigation time, irrigation volume and irrigation cycle are fully based on the water demand parameters of trees to automatically start and close the pumps and automatic irrigation, and the role of human is only to adjust the control program and overhaul the control equipment.

2、Wireless intelligent gateway, intelligent controller, wireless collector, camera and other outdoor devices adopt strict IP66 encapsulation grade to adapt to harsh outdoor deployment environmental conditions. The solar panel power supply is convenient for field deployment, and the built-in solar charging circuit makes the nodes work continuously in the field for a long time, saving power.

3、The device adopts wireless for data transmission, and the construction is flexible and convenient. Users can quickly experience the management improvement brought by advanced IOT technology with less construction cost, saving personnel and improving efficiency.

4、Wireless equipment built-in amplification circuit, support long-distance data transmission.

5、Through advanced IOT technology, users can really view and receive alarms remotely through computer or cell phone anytime and anywhere.

Intelligent drip irrigation water saving system equipment deployment principle

The height of all wireless devices should preferably be higher than the crops in the farmland to facilitate the transmission of wireless data.

The lighting of all solar panels should meet the requirements, solar power needs sufficient lighting.

Soil moisture sensors are recommended to be placed at different depths in order to obtain comprehensive moisture data.
