Residential Emergency Backup Power Supply and Hazard Detector

Abstract

The purpose of this device is to work as a power backup to a house’s sump pump system for when there is a power outage, specifically targeting homes older than the year 2000. It is assumed the UPS will be operating in a basement. The system will be able to operate continuously for 3 hours. If within this time, the battery is low, the pump overheats or fails to start, the client will receive an email notification. In addition, if the battery is bad and/or is not charging when the main AC power is back, the client will also get an email notification.

Our UPS will contain the following components: a smart charger that will be connected to the main power source, an inverter that will convert DC to AC, and a bypass switch. Our system will have one current sensor, one voltage sensor, and an ultrasonic sensor. All the sensors will be connected to the embedded system. This will be key to keep our system working the way it should. The team will also keep in mind any standards that will apply to the system. They shall refer to IEEE, NEC, UL, IP Layer Protocol, and other agency standards with which to comply.
