Build a Power Outage Detector That Sends You an Alert

Build your own smart blackout detector that notifies you the moment the power goes out — even if you're not home. This step-by-step PDF guide shows you how to create both a basic offline version (with LED and buzzer) and a connected version that can send push notifications, emails, or SMS alerts using ESP8266, IFTTT, or GSM.

Ideal for monitoring fridges, aquariums, server setups, or remote properties. No coding experience needed — just follow the clean diagrams and code templates included.

Includes:

• Complete parts list and wiring diagrams
• Easy-to-follow code for Arduino and ESP8266
• Offline and Wi-Fi/GSM alert options
• Upgrade ideas: battery backup, logging, multi-zone detection
• Printable setup card and pro troubleshooting tips

Protect your gear, track blackouts, and stay informed — DIY style.
