UPS: Internal mini UPS 

utilizes 4x AA batteries* 

An internal mini UPS module can be added to a sensorProbeX+ (SPX+) environmental monitoring appliance for the purpose of powering it for several hours.

This module is useful in situations where the SPX+ may face power outages.

An internal battery backup using 4x AA batteries can power the SPX+ for several hours (depending on sensors connected, alerts generated etc). This is ample time to be able to continue to send alerts, and most importantly notify you of the power situation so the main power can be restored.

Ideally combined with the internal cellular data modem, SMS alerts can be sent even if the rest of your network is down.
