Updated December 2013: The seawater temperature monitoring is no longer functional since I moved away and someone turned off the computer. The data I collected for 2010, 2011, and part of 2012 are available as one csv file: 2010-2012_MSC_temps.csv <\/a>\u00a0<\/strong>The time stamps are all in Eastern Standard Time (UTC-5, no daylight savings time) and the water and air temperatures are in degrees Celsius.<\/p>\n

I put together a temporary monitoring system for the seawater temperature and air temperature here at Northeastern University’s Marine Science Center<\/a> in Nahant, Massachusetts.<\/p>\n

The monitoring system is<\/del> was running using some homebrewed Labview<\/a> code and a National Instruments USB-6008<\/a> Data Acquisition Card to read temperatures off of two Analog Devices TMP36<\/a> temperature sensors. The seawater temperature sensor sits<\/del> sat in a bucket of flowing seawater inside the aquarium room. The air temperature sensor is<\/del> was situated in the shade just outside the aquarium room.<\/p>\n

Additionally, there is<\/del> was a float sensor (McMaster-Carr<\/a> PN 46515K81) in the seawater bucket that indicates when the seawater system ceases to flow due to algae clogs or low tides. When there is<\/del> was no seawater flow, the seawater temperature sensor returns<\/del> returned “NaN”, because the temperature data are suspect when there is no water flow. When there is<\/del> was no seawater flow, the system notifies<\/del> notified several users by sending an email through Gmail.<\/p>\n

\"\"<\/a>
In a roundabout way, this old kitty litter bucket is<\/del> was internet-enabled and has<\/del> had the capability to email me when seawater stops<\/del> stopped flowing in our system.<\/figcaption><\/figure>\n
\"\"<\/a>
The $23 float switch obtained from McMaster-Carr senses when there is no longer water flowing into the bucket. The white wire leads to a TMP36 temperature sensor under the black heat shrink tubing.<\/figcaption><\/figure>\n

The system monitors<\/del> monitored temperatures continuously, and saves<\/del> saved the temperatures to a data file once every 5 minutes, using the mean temperatures for the preceding minute.<\/p>\n
