Wireless Temperature Logging Starter Kit

When the power to the base station 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.

If your sensor has a backup memory, 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 base station to the internet is re-established, the server will trigger another set of actions. The data saved in the sensor’s memory will be uploaded to the internet so there should be no gaps in the record.

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 sensor to log more frequently than that, it will use power faster.

Sensors try to use as little power as possible to connect to the base station. 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.
