The Tive trackers use high-quality temperature and humidity sensor positioned inside the tracker behind the sensor opening.
When transitioning the Tive device into a new temperature environment (i.e. a cold room), the device will require up to 20 minutes to equilibrate to the new temperature environment. As a best practice we recommend allowing the device to condition to the new environment temperature for at least 1 hour to ensure accurate temperature readings. If the device is positioned inside a parcel, it may also take some additional time for the cold room temperature to reach the device within the parcel.
When shipping temperature sensitive goods and the accuracy of the temperature measurement is critical, we recommend the following settings:
- Configure the tracker reporting intervals to 60 minutes and a measurement interval of 10 minutes, with the optional Satellite/GPS disabled.
If the tracker is constantly transmitting at a frequent interval, it has a risk to self-heat inside which causes a slight increase in the temperature reading and dries up the air (decrease the humidity). This could reduce the overall temperature and humidity measurement accuracy.
We also recommend disabling GPS positioning, since it also tends to increase self-heating (especially if the tracker cannot get a good GPS signal).
The Tive tracker has the ability to immediately transmit its temperature when the actual temperature goes out of programmed thresholds. For example, for a chilled temperature range (2 to 8 Celsius), the device can be configured to immediately report its temperature when the temperature is above 8 Celsius or below 2 Celsius (out of range). This feature can be enabled by our support team if needed by contacting Tive Client Support team.
For accurate humidity measurement, please avoid covering the sensor opening or putting the tracker inside an envelope as this would reduce the flow of air that reaches the humidity sensor.
Placing the tracker inside a plastic envelope will slightly affect the temperature response time but does not affect the overall temperature measurement accuracy.
