5. Type of sensor used

Several types of sensors are used to transfer data to the irrigation multi-controller unit. Each cell is dedicated to capturing and transferring specific data. The first unit is the Soil Moisture sensor (or SMS), which checks the dielectric constant of the soil surface to estimate the volume water content of the surface. The humidity level is proportional to the dielectric constant reading. An SMS controller can be “On demand” (with the ability to start and terminate an irrigation session) or “bypass” (with the ability to allow irrigation sessions to be within a pre-specified threshold level).
Next is the temperature sensor, which typically uses advanced resistive temperature detector components (RTD) to accurately track soil temperature levels. Note: Soil moisture sensors provide more efficient on-site irrigation than traditional timer-based sprinkler systems. There is no risk of excessive spraying or excessive watering in the former.

6. Integration of climate parameters

While intelligent soil humidity sensors have many advantages, they do not take weather-related factors into account in any way, which remains a limiting factor. Large amounts of water are lost as a result of evaporation and transpiration (ET; Total amount of water lost from plant leaves through transpiration and soil lost through evaporation). Therefore, crop growers should go beyond the SMS controller and start using “smarter” evaporative transpiration controllers or weather-based irrigation controllers (Wbic). These jobs use high-quality weather sensors that can receive real-time weather updates and use the same methods to customize irrigation events. Qoto can also process historical weather information and/or data received from satellites. Other unique characteristics of a particular crop field, from plant type and soil properties, take into account the slope of the ground and the amount of sunlight available. Doing so determines the exact number of watering a place at any given point in time.

7. The role of LED lamps

An intelligent irrigation unit with microcontrollers at its core, as well as pre-tested LED bulbs. When the field sensor reports that the humidity level is below the recommended/threshold level, the bulb glows, indicating that the irrigation event must be activated (that is, the sprinkler valve must be opened). LED lamps are also an important part of the “Fuel tank overflow control model”, which is used in conjunction with powerful ultrasonic sensors. As long as the pump motor is running and the water level in the tank is below the threshold level, the bulb will glow. In essence, LED lamps can be used as portable tools to indicate the state of the pump and sprinkler nozzle at any time.
Readings of sms-es or ultrasonic water tank sensors can be displayed on mobile apps for the convenience of farmers.

8. Placement of sensors

Setting up gateways and pumps and other tools is great, but unless the sensor is properly placed in the field, the “decision” made by the smart irrigation network is likely to be wrong. Experts advise users to ensure that sensors remain in contact with the soil surface at all times, excluding any “air gap”, and distance from irrigation heads, property lines, homes and high traffic areas. For best results, the sensor should be strategically placed in the area where the maximum sunlight is received and within the root area of the plant (depth ~3 “). Soil moisture sensors must be covered with soil, but the pressure around them should not be too high.

9. The rise of smart sprinklers
One of the biggest advantages of switching to an intelligent irrigation system is to save a lot of water. These savings can be increased by about 20% by abandoning outdated sprinkler systems and using nozzles that can spray rotating water in multiple tracks. These “smarter sprinkler nozzles” have a long way to go in ensuring that water is evenly distributed throughout all parts of the oil field (or its specific parts) and are better able to resist changes in weather conditions (wind speed, fog, etc.).
The water released by these rotary head sprinklers is mainly soaked in soil, thus minimizing runoff and other forms of waste. Note: Rainwater sensors are already widely accepted among crop growers in different countries. These sensors are doubled as “shut-off devices” to send signals when heavy rainfall occurs (and thereafter) to stop the automatic sprinkler.

10. More tips for fault detection and repair
Small leaks and cracks in traditional irrigation systems (water tanks, reservoirs, etc.) can lead to significant water losses, thus increasing the already growing global water crisis. More importantly, it is often difficult to manually detect the root causes of these problems and can be a potentially time-consuming event. Installing Intelligent irrigation Tools is a good way to keep these issues at a certain distance. With IoT support, these controllers can detect problems in any irrigation unit in real time, making it easy for users to perform the necessary repairs immediately. Essentially, an Internet-supported irrigation system can “monitor” the condition of water tanks, pumps and other devices-users don’t have to stay in front of their computers all the time.

11. Cost Factors
While some investment is needed to implement intelligent irrigation solutions on site, the cost of sensors is far from excessive. On average, the price of soil moisture sensors is between $150 and $160 trillion, while the more advanced Qoto price is about $300 trillion. By the way, rotary nozzles are ideal for irrigation slopes, priced at about $6 or USD 7 per unit. Large manufacturers also offer special discounts for sensors and sprinkler devices.
Given the potential benefits of upgrading to a smart factory watering system, the cost is relatively reasonable.

12. Challenges
In recent years, the application of the Internet of things in agriculture has developed greatly. Even so, the concept of “smart irrigation” is still a relatively new concept. Most existing intelligent irrigation controllers have many complex features and functions. While these are ideal for large-scale commercial use, such as on golf courses, they are too delicate for smallholder farmers and independent gardeners. The need for hours is to increase awareness and familiarity with these intelligent irrigation systems, especially since user input (for example, crop type, soil, surface slope, etc.) is critical to the performance of these systems. In addition, it is important to remember that the error space in the “smart system” is much lower than the traditional settings.
Mechanical failure or network barriers can have serious consequences. There are many things that can be said to support intelligent irrigation systems. For beginners, they help make the best use of water and ensure that plants are watered evenly. With high-end sensors, they can also consider climate parameters to make irrigation procedures more efficient. Significant savings will be achieved, both in terms of lower waste of water resources and in terms of reducing the need for manual labour. With intelligent “irrigation decision-making” capabilities, advanced IoT supported Intelligent Irrigation controllers are changing the face of agriculture. The field was developing rapidly and it would be interesting to track further developments in that area in the foreseeable future.
