1. Introduction
Refrigerator room temperature remote monitor
system consists of temperature sensors and ET8610 GPRS/SMS FAM, through
monitoring the temperature sensor state, when the temperature exceeds the upper
and lower limits, FAM will send SMS alarm message or send alarm data by GPRS.
2. Function
Over-temperature
alarm:
Refrigerator temperature is above or below
pre-set upper limit lower limit. It can be set to 0-99 seconds of delay; if the
current temperature continuously exceeded the temperature for more than delay,
FAM will send alarm message.
Temperature
alarm clear message:
When the temperature alarm return to normal
value, FAM will send SMS alarm clear message, inform user the alarm clear.
Power
failure alarm:
If the Refrigerator power was failure, FAM
will send alarm SMS. ET8610 FAM built-in lithium battery, even there is no
power, it still can continue to work and send SMS Report City power anomaly.
Sound and
light alarm:
Refrigerator is no power, or over
temperature, it may be sound and light alarm.
Remote
control:
FAM support relay output, user can remote
control relay ON/OFF by SMS command.
System
Expansion:
In addition to detection of cold
temperatures, if we choose the appropriate sensing device, it can detect
circuit current and voltage, light intensity, fluid pressure, gas
concentrations, UPS monitoring; fire monitoring, leakage monitoring, intrusion
and anti-theft Alarm.
