Pet Activity Monitor with Arduino Mega – Know Where Your Pet Is and When Danger Strikes

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

Your pet’s favorite lounging spot, the doors they sneak through, and the safety of your home – monitor it all with one custom panel. Build a wall-mounted system that tracks zone activity with PIR sensors, detects opened cages or rooms via reed switches, and alerts you to smoke or water leaks on a colour-coded LCD. All on the Arduino Mega, with a buzzer that screams when hazards appear.

What You’ll Build

You’ll wire up a pet monitor that reads motion from two PIR sensors, door state from three reed switches, plus smoke and water levels. A 16x2 LCD with I2C backpack shows everything at a glance: green for clear, red for motion in zone A or B, yellow for a door opening, and blinking alerts when smoke or water is detected. The active buzzer sounds a distinct pattern for each emergency, so you know what’s wrong before you even look at the screen.

What You’ll Learn

• Wiring and calibrating HC-SR501 PIR motion sensors for separate pet zones.
• Integrating reed switches to track door, cage, or gate positions.
• Connecting and interpreting analog signals from MQ-2 smoke and water level sensors.
• Programming an LCD via I2C to display real-time, colour-coded statuses with priority alerts.
