# Why Bluetooth logger?

### Why do I need a Bluetooth temperature logger?

Besides reading via USB, the Cydiance Bluetooth loggers provide extra ways of reading data:

a/ Bluetooth direct export

b/ Bluetooth to cloud

It can be super helpful when you,

1/ don't want to open the package if you packed the logger inside

2/ check temperature from multiple loggers around you

3/ want to configure the parameters before using

4/ have the data online and share immediately with clients
