Smart Agricultural Monitoring System using IoT Application for Chili Plants

The use of IoT applications for agricultural in Malaysia is still low. The farmers are mainly using the traditional method compared to modern agriculture by using advanced technology system like IoT application. However, the use of traditional agriculture requires a lot of work and use of labour. This will result their agricultural system become less efficient and quality of production becoming low. Thus, development of system for monitoring and automation are needed to help farmers to manage their agriculture. This paper focused on development of smart agriculture for monitoring and automation system on chili plants using IoT application. The system is developed using Arduino as microcontroller, soil moisture sensor, DHT11 sensor (temperature and humidity), ultrasonic sensor, servo motor, water pump and ESP8266 (Wi-Fi Module). The Wi-Fi module provides internet access to the local network which allows the system to connect to the system and the mobile phone. Soil moisture sensor used to measure the moisture of soil content. DHT11 sensor was used to measure the temperature and humidity of surrounding area of plants. Ultrasonic sensor was used to measure the height of plants. Servo motor is controlled by automation system via Remote XY Apps to provide the fertilizer to the plants. The water pump also can be controlled by the Remote XY apps as to water the plants. Then, data that was collected from the sensors was sent to user via Remote XY apps where user can control the system that is to turn on the servo motor and water pump to fertilize and water to the plants. Therefore, this system can help farmers to manage their agriculture efficiently and improve their quality and quantity of crops.
