Dr Haroon Rashid Hammood Al-Dallal thank you for your contribution to the discussion

The set up uses the temperature sensor, moisture sensor and humidity sensor which measure the approximate temperature, moisture and humidity in the soil. This value enables the system to use appropriate quantity of water which avoids over/under irrigation. Smart irrigation technology uses weather data or soil moisture data to determine the irrigation need of the landscape. Smart irrigation technology includes: These products maximize irrigation efficiency by reducing water waste, while maintaining plant health and quality. The smart irrigation system uses this information to adjust the amount of water it delivers and when it delivers it. System sensors range in type and purpose. They include rain sensors, soil moisture sensors, weather sensors, flow sensors, and others. In smart irrigation system using IOT it contains solar panel, charge controller, battery, Arduino, Ethernet shield, relay, soil moisture sensor, humidity sensor and DC pump. The solar which acts as a source and generates electricity. These charges are stored in the battery via charge controller. Electrochemical Sensors provide key information required in precision agriculture: pH and soil nutrient levels. Sensor electrodes work by detecting specific ions in the soil. Currently, sensors mounted to specially designed “sleds” help gather, process, and map soil chemical data. These include a smart controller, rain sensors, flow sensors, and moisture sensors. As a property manager, you can use all four together to get the most out of your irrigation system. The proposed irrigation system pumps the water to the crop based on the type, area, and date of the plantation of the crop, and these parameters are registered by the farmer through the IoT-based Android App. Temperature, proximity, gas, smoke, and water and air quality sensors provide the input data for environmental monitoring applications. A sensor is a physical device for example a motion detector or a light switch that converts physical events or characteristics. Rain sensors comprise discs that stop or delay the irrigation cycle when they get wet. The primary benefit is water-saving, as the rain will substitute the next irrigation cycle. This automated irrigation system is easily controlled using a computer. It behaves as an intelligent switching system that detects the soil moisture level and irrigates the plant if necessary. This will also save time and energy, as well as minimize energy loss. The IoT-based Smart Plant Monitoring System is designed to monitor and maintain the growth and health of plants. The system works by collecting data from various sensors and then sending that data to a mobile application through the internet.The plant monitoring system is helpful for watering the plants and to monitor few parameters for growth of plants. This system is very used in few areas like nursery farms and in agriculture. Granular crop-level monitoring can help growers identify and remedy problematic and potentially destructive conditions. Smart sensing helps 30MHz customers prevent sunscald, optimize nutrient and water delivery, and prevent moisture-borne diseases by tracking dew point and soil moisture.
