Figure 2.3 illustrates the proposed prototype model of the field with Agro-IoT system.

A total of 6 types of sensors have been used to build the prototype model for the integrated system. The soil condition is getting measured by temperature, moisture, and ph sensor and sends the data to beaglebone black. Ultrasonic sensor senses the water level of the field and when it detects a lower voltage value than the predefined threshold value, then it send a signal to beaglebone black so that automatically the water pump will start to provide water in field. When the water level is enough in field the sensor again send the signal to beaglebone black to stop the water pump automatically.

Figure 2.3 Proposed prototype model for integrated Agro-IoT system.

The camera plays an important role in the prototype model. It captures image of the crop field in every milliseconds and sends the processed data to the image server which is connected to beaglebone black. Through the camera and with our proposed image processing algorithm three most important things i.e. pest, weed and fire can be detected easily. If the proposed image processing algorithm detects the amount of pest is severe, then through beaglebone black the sprinkler for spraying pesticide will get active and spray automatically. So pest can be controlled efficiently by the system without the farmer. When the proposed algorithm detect weed, it sends the signal to beaglebone black and farmer can get the alert via sms to control the weed by themselves only. In case of fire in the field, the proposed algorithm detect the region of fire and send the signal to beaglebone black so that the sprinkler for distributing water to the field gets active and take action to resolve it. Thus pest, weed and fire can be detected and controlled efficiently. Proximity sensor is also playing an important role to find any intruder. In the present of any animal in the field like cow or goat, the sensor sends the signal to beaglebone black and automatically it will send it to the corresponding device to uplift the iron railing from all the four sides of the field. Thus, no animal except bird can enter the field. All the device is getting active by utilizing the eco-friendly energy source of solar panel. Farmers get alert of every above mentioned condition via sms. For future records, the processed data from beaglebone black also get uploaded in cloud storage and an interface can be used by the farmer to get all the records of the field anytime from anywhere.
