IoT Smart Gardening Herbal Plant System Analysis on Aloe Barbadensis miller, Salvia Rosmarimus, Clinacanthus nutans and Curcuma

The Internet of Things (IoT) is an emerging technology developing recently. The technology of IoT allows users to communicate with controllers and sensors which is widely used in the agricultural sector such as farming and weather forecast. Recently, it has been identified that herbal traditional home gardens are difficult to monitor where herbal plants are sensitive and need a proper monitor. This research has developed an IoT smart gardening for herbal plant systems that helps to analyze four types of herbal plants which are Aloe Barbadensis miller, Salvia Rosmarimus, Clinacanthus nutans, and Curcuma. The system was designed using a NodeMCU ESP32 controller, soil moisture sensor, and DHT11 temperature and humidity sensor. The collected data was monitored in real-time on the Blynk platform via mobile phone and web browsers during a sunny day and a rainy day. The result presents that the highest temperature on a sunny day was captured is 30°C and the lowest was 26°C. However, during a rainy day, the highest temperature captured is 28°C and the lowest was 24°C. The highest humidity percentage on a sunny day was 80% and the lowest was 40% while the highest percentage of humidity on a rainy day was 98% and the lowest was 68%. The soil moisture data captured the water content of the soil of each herbal plant on a sunny day has been lost due to high temperature compared to each herbal plant barely lost the water content due to low temperature and high humidity percentage condition. The comparison showed that temperature, humidity, and weather could affect the water content in the soil. This research has significantly improved the agriculture sector in monitoring herbal plants towards moving from traditional planting with an IoT system concept.
