Pet Activity Monitor Kit
Build a Pet Activity Monitor with Arduino – Motion Logging & Camera Trigger 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.
This kit transforms a standard Arduino Uno into a surveillance-grade pet activity logger. It uses dual PIR sensors to capture every movement, stamps each event with a real-time clock, and saves a metadata log to microSD. A relay output can power a wired camera or trigger a DVR snapshot, giving you both a data trail and optional visual evidence of what your pet does while you’re out.
What You'll Build
You’ll create a standalone monitor that detects motion across a wide area, displays the last trigger time on an OLED screen, and stores a timestamped log file on an 8GB card. The integrated relay switch can turn on a camera (up to 10A) for a set duration on each event—perfect for pet owners who want to cross-check activity with video clips.
What You'll Learn
- Interfacing HC-SR501 PIR sensors with Arduino to create a dual-zone motion detection system and adjust sensitivity/delay on hardware.
- Logging time-stamped event data to microSD using a DS3231 RTC, including file creation and append operations for reliable, tamper-proof records.
- Programming a 0.96-inch OLED display to show real-time status, last motion time, and SD card usage without a PC connection.
- Controlling a 5V relay module to safely switch an external camera or alarm, including diode protection against back-EMF and isolation techniques.

Who This Kit Is For
B.Tech ECE/EEE students building a final‑year embedded systems prototype will find the data logging and relay control directly applicable to surveillance and automation projects. Smart India Hackathon participants can use the kit as a ready sensor‑actuator subsystem. Hobbyists who want to replace a basic pet camera with a hackable, log‑driven monitor will also enjoy the deep‑dive into Arduino programming and hardware integration.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with your AI companion that has full context of this project; it can guide you through code debugging, wiring checks, and relay configuration. For trickier issues, WhatsApp support from our Bengaluru team is just a message away.
Can I connect this to my home Wi‑Fi or send alerts to my phone?
This kit is a standalone logger and does not include Wi‑Fi hardware. However, you can extend it with an ESP8266 or Ethernet shield, and the AI assistant can suggest integration paths if you want cloud alerts.
Will the PIR sensors work through a window or for outdoor pets?
PIR sensors detect heat changes and typically do not work through glass. For outdoor use, place the sensor in a shaded, dry spot. The kit includes two sensors so you can position them indoors near pet doors or favourite resting areas for accurate detection.
How do I power the external camera with the relay?
The 5V relay module acts as a switch; you provide the camera’s own power supply through the relay’s normally‑open contacts. The relay is rated up to 10A at 250V AC or 30V DC, compatible with most wired CCTV cameras. The kit includes a 1N4007 diode to protect against inductive spikes if you’re switching anything with a coil.
Pet Tracking — PIR triggers timestamp log and snapshots metadata to SD. Relay triggers external camera power on motion.
