Outline Overview Controller Temperature Sensor Setup Results Conclusion Future Work 2
Overview The 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 and/or relay triggering when monitoring conditions are out of the desired range. 3
Controller Barix BarioNet IP Enabled Programmable Controller ◦ Built-in Web Server that is completely customizable ◦ 2 Relay Outputs 250VAC) ◦ A Dallas 1-Wire interface that can support up to 50,1-Wire temperature sensors ◦ Operating temperature:0 to 50°C / 32 to 104°F ◦ Password protected 4
Controller 5
Controller 6 PIC16F877A SCHRACK PEO14005
Controller 7 [3]
Temperature Sensor Tamperproof SS Flat Plate 1-Wire Temperature Sensor ◦ A DS18B20 digital sensor with 12-bit resolution ◦ +/- 0.5°C accuracy over range of -10 to 85°C ◦ Measures Temperatures from -55 to 125°C (-67 to 257°F) ◦ A flat plate sized to fit a single gang box 8
Temperature Sensor Note: The 1-Wire interface pin (DQ) provides power to the device when used in parasite power mode. V DD must be grounded for operation in parasite power mode. 1 – GND 2 – DQ (Data I/O 1-Wire interface pin) 3 – V DD DS18B20 9 [5] [6]

Results Challenges ◦ IP configuration ◦ SMTP setup ◦ delay (1min. 50sec.) ◦ Interpreting settings 13
Results Success ◦ Confirmed proper operation of relay triggering when temperature is out of set range ◦ Confirmed proper operation of notification when temperature is out of set range 14
Conclusion The BarioNet 100 has provided remote access automated temperature monitoring for the ECE Power Lab via and/or relay triggering when monitoring conditions are out of the desired range. 15
Future Work Expand monitoring to include: ◦ Two temperature sensors ◦ One hydrogen sensor ◦ One air quality sensor ◦ Two vibration sensors 16
