ON/OFF Automation System for a Uninterruptible Power Supply (UPS): Adding schedule function

This Arduino project was connected to a UPS to power on/off with RTC alarms (its purpose is to extend battery life). In addition, the schedule and shutdown times may also be configured by a HMI via USB port.

Features

• Isolated voltage sensor.
• Configurable RTC DS3231 alarms (schedule - hour, minute and day of week).
• Audible alarm when UPS inverter is working (main supply has failed).
• Alarm reset button.
• HMI communication via USB port.

IMPORTANT

This new version has not been tested yet, however, it was based on a tested and functional one.
