Savi SensorTag ST-676-I ISO Container Door Tag with Sensors Installation Guide 7
Intrusion Detection Sensors
The ST-676-I tags include door and light sensors. The door sensor monitors
the amount of pressure between the door and the device. If the door is open
and the device has not been electronically unsealed, the device sends a
message to the monitoring software indicating that the device has been
tampered. It also writes the time and date of the tamper to an event log. The
device also includes a light sensor that triggers an alarm if light is detected
inside the container.
Environmental Sensors
The environmental sensors on the ST-676-I tags monitor the temperature
and humidity within the container. You can set the maximum and minimum
values, and if the temperature or humidity rises above or falls below this
range, the device writes the time and date of the breach to the event log. For
example, if you are shipping a product that needs to be kept at temperatures
between x and y degrees, you can set the ST-676-I tag to record the date and
time whenever the temperature breaches the maximum or minimum value.
Tamper-Protection Plate
The tamper-protection plate’s right angle flaps are bent to extend and
protect the gap behind the plate as well as the tag plate. This plate prevents
anyone from inserting a foreign object in an attempt to hold the tag plate in
the closed position.
RFID Communication Module
The communication module is positioned on the outside of the container
and operates at 433 MHz. This enables the Savi SensorTag ST-676-I ISO
Container Door Tag with Sensors to communicate back to the Savi network
with excellent RF performance in both heavy metal and non line-of-sight
environments.
