"The internet of things (IoT) is the network of physical devices, vehicles, buildings and other items—embedded with electronics, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data"-------- wikipedia

As the world changing, the internet has become Indispensable. With the power of it, we could do lots of things. And we are going to combine the great power of Internet into our device.

Our device contains two concepts, automatic system and non-toxic agriculture. Our device has multiple functions which can detect and eliminate pests automatically. We integrate high-technology into agriculture. We subvert the public perception of the traditional agriculture. In our device, it makes up of three parts, detector, controller, and client.

Inside the automatic system, it's combined of three parts, dectector, server, and client.

First, inside the detector, we use the product of NCTU_Formosa iGEM team 2014 which called PBAN to attract few specific kinds of pests into our device which will count the number of each kind of pest. Second, the controller will depend on the data from the detector the decide whether to spray the PANTIDE or not. Last, the client will receive the data and tell the user whether the are bugs invading your farm or how is the condition of the farm.

Our detector contains several parts. The main part is to catch different kinds of pests and calculate the numbers. It's a double layered box with a Inverted pyramid inside it. Inside the pyramid, we separate the volume into several parts. Each parts have one kind of pBAN to attract a specific type of pest. When a bug comes into the device, the infrared light will be cut off, so we can count the bugs inside each volume to know which pest are more. Beside, we also use the Hygrometer to know whether the dirt is too dry or not. We optimize the value of the humidity according to which plant we are going to plant. And also, we will record the wheather condition to show the user.

And the controller, we use the IoT board linkit smart 7688 duo, released by MediaTek, which has a MPU and a MCU. The MCU will get the data from the detector and sensors and send to the MPU, then the MPU will do a few computation and translate the data into the information we want. And communicate with the server through WiFi, receiving the command from it and sending the information to the server. Also, the MPU will send the command to the MCUto tell it what should it do.

For the server part, which is the most important part of the IOT system, it's the central of our device. On the server, most of computation is done here, and it also have a SQLite database on it saving the information and the result of computation. Beside, it will send the information we want to the client through the internet.

At the client, we write a mobile app for it. Inside the app, we will have a panel to show us how is the condition of our farm. we can also use the app to turn on/off the sprinklers at any time any where as long as we have access to the internet.

With the detector, we can know the situation without really going to the farm. With the server, we can grow the plant without labors. With the client, we can still manage our farm remotely. With all the parts above, we make up our device.
