Data are recorded over time, providing a record of conditions. Sensors monitor temperature, relative humidity, carbon dioxide, solar radiation, and other factors that can affect artifacts. Monitoring and control can be based on time or measured parameters, or a series of events. Systems can initiate shut-downs, sound alarms, and report conditions by calling out to pagers, radios, or phones. Our voice-synthesized modems can speak to you.
Systems have their own power supply.
They can recognize and report ac power loss while continuing to measure and store data. Systems support hardwire or wireless communication to a central computer, making real-time data analysis and display easy.
