Temperature also plays a role in battery life. The battery life estimates in the online spreadsheet
assume room temperature, but temperatures close to the maximum and minimum ratings will
have a negative impact on battery life. For example, battery voltage tends to be lower in cold
temperatures and the internal circuitry needs a certain minimum voltage to operate properly
before it will shut down. Thus, battery life will tend to be shorter when running the sensor in cold
environments.
The battery voltage is reported by the supervisory messages as well as a low battery indicator.
See the section on Message Protocol for more detail.

The sensor can be triggered to send test messages by placing a magnet next to the triangular
notch on the side of the sensor. There is a small magnetic reed switch that will detect the presence
of a magnet and send a message. This can be used for diagnostic purposes to ensure the sensor
is within range and connected to the network.

This section defines the protocol and message definitions for the sensor.
Radio Bridge provides a web-based console at console.radiobridge.com
to configure and monitor sensors. Usage of this console is highly
recommended for most customers rather than implementing the
protocols defined in this section.
If the standard Radio Bridge console (console.radiobridge.com) is not used, refer to this section
to decode the sensor data and configure the sensor through downlink messages.

Battery voltage will be lower in cold temperatures and thus battery life
will be reduced in cold environments.
