Technical Details of Logging Seawater Temperature

Block Diagram This diagram shows the basic components required for collecting temperature readings from seawater and transmitting the data to a base station where it can be collated into a database for analysis. To the left is a schematic of 10 temperature sensors, spaced 1 metre apart and immersed in seawater to a depth of 10 metres. This is connected to an Ardiuno Uno microprocessor which has been program ...
