OverviewThe scope of this project is to provide remote access automated monitoring for the ECE Power Lab.

An IP enabled controller will be used to monitor a temperature sensor at a select location of the lab and provide notification via email and/or relay triggering when monitoring conditions are out of the desired range.

ResultsSuccess

◦Confirmed proper operation of relay triggering when temperature is out of set range

◦Confirmed proper operation of email notification when temperature is out of set range

15

ConclusionThe BarioNet 100 has provided remote access automated temperature monitoring for the ECE Power Lab via email and/or relay triggering when monitoring conditions are out of the desired range.
