Automatic monitoring and control of shrimp aquaculture and paddy field based on embedded system and IoT

Aquaculture is the farming of aquatic organism in natural or controlled marine or freshwater environments. The real-time monitoring of environmental parameters are very important for both shrimp aquaculture and paddy farming. Here, an electronic system is proposed for the efficient monitoring and effective control of different environmental parameters related to the paddy field and shrimp aquaculture. The proposed system is implemented as an embedded system to monitor and control the important environmental parameters with the help of sensors and actuators. A set of different types of sensors are placed in the cultivation field and each of them are connected to a common microcontroller board built on an Arduino UNO board. The micro-controller will monitor the sensor values and these real-time values are shared to a data logging system implemented on a Raspberry Pi based single board computer. The real-time sensor values can be logged into the SD card of the Raspberry Pi. The actuators such as pump and aerator will be turned on and off automatically by the Raspberry Pi in accordance with the threshold values of different environmental parameters. Moreover, the farmer is also given a facility to control the pumps and aerators through a latest trend in embedded system technology called the Internet of Things(IoT). The farmers can use a social media open-source Android app called Telegram for monitoring and controlling the system. Also, the real-time temperature and humidity values from the sensors are validated by using the information collected from a weather forecasting website. If any abnormality in the environmental parameters are observed, the system will notify the farmer by generating alert SMSs through a web-service application called Twilio. The installation of such a system in the paddy field will definitely help the farmers to increase the yield in a better environmental condition.
