Remote Data Logging at Loch Lunndaidh Using Sensors to Monitor the Quality of Water in a place that is difficult to get to.

At Loch Lunndaidh a remote data logger monitors the water quality. The loch is in the hills and not on a road so it is difficult to get to. North Sea Birmingham Site of Data Logger

To get to the data logger you have to : 1. Walk to the top of the very steep hill from the farm for about 1.3 km 2. Walk along the track another 0.7 km

This is the loch with the water coming out of it. The data logger uses sensors to automatically monitor the water in the stream so that it does not need someone to go there to to take the readings The data logger can take lots of readings over a very long period of time and never forgets to take a reading. The readings are more accurate than readings taken by humans. Data logging equipment like this is very expensive If the sensors or the data logger stops working properly it could send back incorrect data or no data at all. Advantages and Disadvantages

The sensors are placed in and around the water The sensors record data about the water and send the data to the data logger on the stream’s bank. The measurements include the oxygen level, rate of flow, depth and chemical content of the water Data logger Position of sensors

1. The data is sent to the data logger which has a solar panel to provide the power to keep it running. 2. The data is then set via a satellite to the computers of the organisation which is monitoring the water. 3. The collected data is then analysed to give information about how pure the water is.

Your tasks Task 1 Look at the PowerPoint presentation again. Use the worksheet or copy and paste these questions into a MS Word document and answer them.worksheet 1.What is the purpose of this remote data logging system? 2.Why is remote data logging used in this situation? 3.What sensors are used? 4.What happens to the data from the sensors? 5.What does the data logger do with the data from the sensors? 6.How is the power provided for the data logger? 7.Why do they use this type of power for the data logger? 8.What does the company use the data for? 9.What are the advantages of using remote data logging? 10.What are the disadvantages of using remote data logging? Task 2 Use your answers to create a leaflet about this data logging system
