Automate Your Pet’s Night Routine — Arduino Uno Pet Activity Monitor with Light Dimming and Thermostat Control

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 thrives on routine, especially at night. This kit lets you build a system that senses when your pet settles down, then automatically dims the room lights and switches on a low-power thermostat to maintain a comfortable sleep temperature. Using an Arduino Uno, a PIR motion sensor, light-dependent resistors, and a real-time clock, the circuit monitors activity and time to trigger a relay — perfect for a pet corner, indoor kennel, or small habitat.

What You'll Build

You'll assemble a fully functional pet activity monitor that reads ambient light levels, detects the last movement before bedtime, and uses a pre-set evening schedule to activate the relay. The OLED display shows the current time, light intensity, and whether sleep mode is active. Once your pet is quiet and the scheduled hour arrives, the relay can dim a connected lamp and switch on a heat mat or fan (via an external appliance). The entire logic lives on the Arduino, programmable through the Arduino IDE.

What You'll Learn

• Calibrating and interpreting readings from two LDRs placed in the pet's environment
• Integrating an RTC (DS3231) to enforce time‑window automations
• Using a PIR sensor to detect stillness after movement subsides
• Controlling AC appliances safely through a 4‑channel relay module
