GPRS Temperature/Data Logger

1. Brief introduction
1.1 Introduction
The GPRS Temperature/Data Logger inbuilt industrial quad band GPRS Engine inside, it provides 4
temperature input that each temperature sensor supports ultra-high-high-low-ultra-low 4 level
monitoring, and 1 digital relay output. It can be used for field temperature monitoring in the worldwide.
And the internal memory can save the historical for half a year for review. It provides daily report,
schedule upload, event upload by the GPRS to monitoring center or by SMS to the user mobile
phone directly.
Just dial from Authorized User number or send SMS to the GPRS Temperature Logger, the relay
output will be switched on or off. There are no call costs, the GPRS Temperature Logger rejects the
call from authorized number then carries out the turn ON/OFF action.
In one word, the GPRS Temperature Logger is the best choice for lots of temperature monitoring
applications.
