Introducing the Tempo™ Environment Monitor

The environment affects us in so many ways, from how we feel through to how productive we are. The things we care about are also affected by the environment, from pets through to collectables.  In the commercial world many products are legally required to have their temperature monitored and recorded even before considering the expense and loss of reputation that products spoiled by incorrect storage conditions cause.

Blue Maestro's Tempo™ Environment Monitor is a powerful Bluetooth Smart sensor unit that is compatible with iOS and Android smartphones and tablets.  Internet connectivity is also available with Tempo Anywhere™, Blue Maestro's battery powered Wi-Fi gateway unit, meaning that Tempo™ Environment Monitors not only communicate directly with smartphones, but their data can be routed to the internet for storage and web browser accessibility.

Perfect for a range of use cases

We have designed Tempo to be the ultimate environment monitor that combines a range of powerful features with cool aesthetics that means it looks good inside as well as out - on a coffee table or in the garden - in a factory or in a vivarium. It is robust so it can be used in industrial and commercial applications. Powered by 2xAA batteries that are easily replaceable, Tempo is wireless making it easy to use and deploy. Simply turn it on, download the free app and you are done!

Powerful Range of Features

Tempo has a range of features that makes it one of the most powerful environment monitors on the market today. From the ability to set the frequency of data recording to being able to individually re-calibrate the sensors should you so wish. With a long battery life and memory that can hold up to 30 days of hourly data, Tempo offers commercial level sophistication in a beautiful form and competitive price point.
