Cat Pantry IoT Detector
Smart Home Sensor Network
Developed For:Independent Project
The Objective
My cats figured out how to open the pantry and eat my bread, so I engineered a custom IoT security system. I paired a PIR motion sensor with an Arduino and an NRF24 radio module to transmit activity alerts to a Raspberry Pi base station. The Pi parses the radio packets and triggers a custom Discord bot to immediately ping me when motion is detected. It's a scalable architecture that could easily be adapted into a larger home security network.
The subjects in question
Technical Stack & Optimizations
[How did you format the telemetry packets sent over the NRF24? Did you have to implement any sleep modes or power optimizations for the Arduino, or is it wall-powered?]
