Can I store data?

Yes, the TUNDRA stores ambient temperature, ambient relative humidity, and probe data (if using the TUNDRA-Probe) by default. If you do not need to store one or more of these data-types, storing can optionally be disabled.

How long is the data stored?

Up to 3000 entries each of ambient temperature, ambient relative humidity, and probe data can be stored before the TUNDRA begins overwriting the oldest data. With default reporting settings (1 report/hour), this is equivalent to 125 days of data.

What is the difference between ambient temperature, probe temperature, and MCU temperature?

• Ambient temperature is measured by a transducer on the circuit board inside the enclosure and is supported by both the Base and Probe variants.
• Probe temperature is measured through the probe voltage reading and converted by a formula. The probe can be used to access remote areas where the TUNDRA itself cannot go, such as inside of a very cold freezer.
• MCU temperature is the temperature of the MCU on the circuit board. This is used to monitor the health of the MCU and may differ from the ambient readings.

Are the temperature and humidity instant-read?

Since the ambient data is measured from inside the enclosure, it takes some time for the ambient air to flow through the humidity vents and equalize with the inside of the TUNDRA. The ambient temperature takes about 5 minutes to equalize and the relative humidity takes about 80 minutes.
