Description
Overview
GAOTek temperature sensor with GPRS, SMS, ethernet, and programmable logging has built in UPS feature providing user alert of AC power loss. During power loss, operation is backed up by internal rechargeable battery. Its internal 4 MB memory logs about 30,000 data records, and expandable to 32 GB with SD card. Data can be uploaded to server as fast as 5 seconds interval, or 24 hours to save power. Programmable data logging intervals start from 1 minute up to 24 hours.
