Appendix 6: Concept Pros and Cons

Concept Pros and Cons

Concept	Advantages	Disadvantages
1. Data from fixed sensors is transferred using RS232 software, using cable to send to computer	1. Data transfer without hassle. 2. Less human power 3. Save time 4. Test automatically 5. Rate of transfer is constant. 6. Sensors’ result is free from other ponds result.	1. Complicated installation. 2. High cost. 3. Many sensors are needed. 4. A lot of wiring involved.
2. Data from fixed sensors are transferred through wireless	1. Less human power. 2. Save time. 3. Test automatically. 4. No wire involved. 5. Clean look system.	1. Easy installation. 2. Very high cost. 3. Rate of transfer depends on the wireless strength/ not stable. 4. Many sensors are needed. 5. Data mixing. 6. Range constraints.
3. Portable sensor with a memory storage device is used to transfer data to computer	1. Only 1 sensor with multiple functions is needed. 2. Very easy to install. 3. Can store data automatically. 4. Data transfer is certain. 5. Cost is lower. 6. High speed data transfer using USB port.	1. Time consuming. 2. Man power is needed. 3. Test water individually. 4. Data is kept in a device then only transfer to computer.
4. Pipe water is connected from every pond to the lab, testing is done inside the lab.	1. Few sensors are needed in the lab. 2. Less human power. 3. Data can be recorded straight away in computer. 4. Low cost.	1. Complicated installation (A lot of piping involved) 2. Maintenance cost is high 3. Cannot be used for a farm which has many ponds. 4. Time consuming. 5. Test the water individually.
