A constant record of temperature, even if the power goes out

The WirelessTag Logger features in-built backup memory. If the Tag loses contact with the Tag Manager, it keeps recording temperatures. When the connection to the Tag Manager is re-established, the Tag will automatically upload its stored data.

This makes this model ideal for sensitive applications where results must be recorded with no gaps in the data e.g. a vaccine fridge.

Do I need the base station?

Yes. This system requires a Tag Manager in order to save temperature data to the internet. However, one Tag Manager can handle connections from dozens of Tags at once, provided they are all in range.

Can't I just connect the Tag to my wi-fi network?

No. The Tag transmits data on a frequency of 433Mhz. This is completely different to the wi-fi connection.

It’s actually the same frequency used by things like garage door openers or remote control toys. This frequency allows better penetration through fridges, cool rooms and walls.

What happens when the power goes out?

When the power to the Tag Manager goes out, the internet server will recognise that it has lost connection to the base station and signal an alert.

Depending on how you have configured your account, this can do a number of things including sending an email and sending a notification to your phone.

This Tag has a backup memory, so it will continue to log temperatures and save that data to its internal memory. It can save over 8,000 readings – about 28 days of readings five minutes apart.

When the connection from the Tag Manager to the internet is re-established, the server will trigger another set of actions. The data saved in the Tag’s memory will be uploaded to the internet so there should be no gaps in the record. 

How long does the battery last?

The battery is a fairly standard 3V coin-cell battery (Model CR2032). You can buy them at supermarkets, pharmacies, hardware stores, etc for a couple of dollars.

How long the battery lasts is dependent mainly on two factors: the sampling rate and the connection strength.

The sampling rate is set to a maximum of 5 minutes, and this is the recommended interval for most applications. If you configure the Tag to log more frequently than that, it will use power faster.

Tags try to use as little power as possible to connect to the Tag Manager. If they are a long way from the base station or there are a lot of obstructions to the signal, then they are forced to use more power to make a connection, draining the battery faster.

In the worst case, battery life can be quite short – as little as a few months. Most of our customers report battery life of between 10 and 14 months.

How do I replace the battery

Replacing the battery is quite a quick process, but it can be a bit fiddly.

Here is a video that explains the process…
