Application with the Wireless Sensor Network in Smart Farms

Abstract

Growing green oak lettuce by controlling the factors affecting growth requires continual attention to develop the lettuce plant. For instance, watering must be consistently moist rather than soaking wet. Therefore, farmers have to inspect humidity in the soil regularly and apply enough irrigation to keep soil moist. For this reason, the Internet of Things (IoT) was applied to resolve the mentioned problem. The proposed technology aims to use the sensing system to measure the degree of temperature, humidity, and soil moisture in order to reduce the burden of farmers by dividing the research methodology into 4 steps: planning, analyzing, designing and implementing. The findings showed that the sensor could detect the degree of temperature, air humidity, and soil moisture as well as transfer the data from measurement via MQTT protocol to the server node for processing every minute. If the detected degree of soil humidity is lower than the set value, then the server node will start the water pumping system in the green oak lettuce farm. The soil detection system will check the farming plots automatically and save farmers’ time and expenses. The proposed system requires less amount of watering time (1 minute) than the traditional method (7-10 minutes) and decreases water consumption from 3-4 liters to 2-3 liters per minute.
