BackgroundThree Master-Bilt V39LX094XX commercial

walk-in refrigeration units Used to store research material for MSU

faculty, graduate, and undergraduate studiesNo way to remotely monitor if any

malfunction occursValuable research material lost in the past

due to compressor failure

Page 4: Refrigeration  Montitoring  System

Problem StatementNecessity to alert client of malfunctions and

constantly record internal environmental data

Objective is to research, design, and implement a system that does this

Page 5: Refrigeration  Montitoring  System

Project AssumptionsRemote accessAlertsData LogUser friendly

Page 6: Refrigeration  Montitoring  System

Research ObjectivesSystem must monitor temperature and relative humiditySystem must allow for real-time monitor, display, and alert when

system failsSystem must meet/exceed these design requirements

Temperature accuracy: Minimum +/- 0.5°F Temperature resolution: Minimum +/- 1°F Humidity accuracy: Minimum +/- 0.5% Humidity resolution: Minimum +/- 1% System must be able to log measurement data Must be able to record data in time intervals as small as 1 minute apart

Research best-priced and most highly functional alternatives for monitoring units

Formulate block diagram to compare all alternatives prior to selection

Shielding DeviceConsists of a set of three adapters that

convert the conduit from ¾ “ to 2”. Then drilled holes at an angle to allow air to enter probe sensing environment from below but reduce effect from high airflow.
