Log Every Electricity Outage with the Arduino Nano Power Outage Duration Logger Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

That hum of a fan going silent, the sudden dark—power cuts are a daily reality across India. But how long did it last? When exactly did it hit? This kit puts you in control. You’ll build a compact, battery-backed logger that detects mains loss instantly via the INA219 sensor, stamps start and end times using a DS3231 real-time clock, saves each event to a MicroSD card, and displays the latest outage history on an OLED screen. Perfect for monitoring home supply reliability, validating UPS performance, or documenting lab power disturbances.

What You'll Build

A self-contained outage logger that sits between your mains adapter and the wall. The moment your electricity fails, the INA219 senses zero current and wakes the Arduino Nano from low-power standby. The DS3231 records the exact time, the OLED confirms the event, and once power returns and the battery recharges, all saved timestamps can be read from the MicroSD. You’ll have a permanent log of every cut—its start, end, and duration—right at your fingertips.

What You'll Learn

• Interfacing INA219 current sensor to detect loss of mains supply
• Programming DS3231 RTC for precise timestamping even during power-down
• Logging structured outage data to MicroSD card in CSV format
• Designing a battery-backup system with TP4056 charging and LiPo management
