The fresh water resources in the world are very scarce, only 3% of which can be obtained by human beings. In the water resources that the mankind consumes, water usage of agricultural production occupies 70%! Undoubtedly large water users. Within the global scope, detecting soil moisture helps farmers make effective and wise irrigation decisions, too much water in the soil can lead to waterlogging and pests, and lacking of water can lead to stunted crops and reduced production.
Basic requirements of agricultural IOT :
1. Even if in remote areas, the sensor can precisely collect the soil water
2. Able to reduce water usage
3. Able to integrate into be automatic detection irrigation system
1. USRIOT ’s LoRa module can realize mass connection within a range of more than 3500 meters.
2. LoRaWAN Ad-Hoc networks can be deployed in any region, certainly including any remote area. There is no need for base station equipment at all compared to cellular network.
3. Very easy to install.
4. Precisely control so as to help customers to reduce 30% water usage.
5. Replace labor, reduce the labor cost.
USRIOT ’s customers——National forestry administration
Our country has been carrying out ecological restoration work such as returning the grain plots to forestry and grassland in northwest China. One organization, which cannot be named, is responsible for ecological restoration of 100,000 mu desertified land on the Loess plateau, which is of great significance for the ecology of the whole country, but this work will consume a huge amount of fresh water resources, in Loess Plateau, where water resource acquisition costs are extremely high, precision irrigation is essential. They use a USRIOT ’s module and the gateway to build a powerful agricultural IOT solution.
At present, the ecological restoration work has achieved remarkable results, and their reproducible solutions have markets in Africa, America and other regions. In Jiangsu, Zhejiang and other places, mulberry plantations have adopted this solution.
“We will first use experimental data to determine the optimum moisture content for mulberry trees,” says the project leader,“We use drones and satellites to accurately map terrain, with high efficiency and large scale.”
In order to ensure the moisture needed for the mulberry trees used to supply silkworm cocoons, they specially design and produce a temperature and humidity sensor system, they test all network transmission technology, such as nb-iot，gprs，4g,wifi, all are unsuitable, finally they select LoRa.
Scale and visualization operation
This solution has the advantage of low cost, wireless network and remote control system, providing farmers with real-time access to the soil moisture status of crops. The soil is uneven, and the way they keep moisture in different areas is different. It can make data more valuable and guide farmers to make irrigation decisions.
In addition, they cooperate with USRIOT to construct their private cloud platform, and develop the application software, you can see all aspects of irrigation data and implement decisions through mobile phones, computers and Ipad.
This system can reduce the amount of water used in agricultural production by 30%, and the amount of water saved in one year is equivalent to the annual water consumption of Jinan City with a population of 7 million.
