At present, the world is close to 7.53 billion people. A recent study found that, on average, 33% of the world’s population suffers from a shortage of water resources in some form or other form. By 2030, that number is likely to rise to 50%, a clear highlight of the alarming rate at which water scarcity is widening. Interestingly, about 70% of the world’s water intake is used for irrigation, which is exactly where most of the waste water occurs. About 60% of the water used for irrigation is lost due to evaporation and transpiration, land runoff or simple and inefficient original use methods. This, in turn, reveals the importance of intelligent irrigation-supported by the Internet of Things (IoT)-which can largely manage the world’s rising pressure on water resources. Next, we’ll focus on some of the interesting facts about Smart irrigation:
Intelligent irrigation is an important part of precision agriculture. by a) irrigation at the right time, b) minimizing runoff and other waste, and C) accurate determination of soil moisture content, thus finding irrigation requirements, helping farmers avoid waste of water resources and improving the quality of crop growth in the field anywhere. The replacement of manual irrigation with automatic valves and systems also eliminates human error factors (for example, forgetting to close valves after watering fields) and helps save energy, time and valuable resources. In general, the installation and configuration of intelligent irrigation systems is also fairly simple.
Intelligent microcontrollers (as “information portals”) are at the heart of automated irrigation infrastructure. The soil moisture sensor and temperature sensor placed on the field send real-time data to the microcontroller. Typically, the “humidity/temperature range” is specified, and as long as the actual value exceeds this range, the microcontroller automatically opens the pump and the pump is mounted on the pump through the output pin. The microcontroller is also equipped with a servo motor to ensure that the pipe actually watered the field evenly so that no area is clogged or too dry. The entire system can be managed by end users through dedicated mobile applications.
Intelligent irrigation allows growers to remotely monitor and irrigate their fields without any hassle.
The flow of information into and out of a centralized gateway (here is a microcontroller) must be supported by a stable Internet service. Wireless low-Power networks (for example, LoRaWAN or Sigfox) can be easily used to power sensors. These sensors send field information to the user’s local computer or cloud network (as needed). The system can combine information with other inputs from third-party services (for example, local weather channels) to achieve “smart irrigation decisions.” For example, if there is rain in the forecast, water will not be released-even if real-time data indicate that the field needs to be irrigated.
Recalculations are also completed on a regular basis. Note: Intelligent irrigation systems can save up to 45% of water during the dry season compared to manual watering systems, saving 80% of water during the rainy season.
In an automated irrigation infrastructure, there is no room for waste of resources. As a result, cost-effectiveness can also be obtained. By replacing traditional irrigation systems with fully automated irrigation systems, there is little chance of crop death due to excessive (or inadequate) watering, which means that farmers do not have to worry about changing plants frequently. In addition, since both smart agriculture and smart irrigation are about faster and healthier crop growth, the average crop cycle has been shortened. This means that it is possible to increase annual production. IoT power irrigation tools can also be used for lawns, gardens and landscapes.
