Accurately measuring activity and feeding is frequently important in laboratory animal research, whether for welfare-monitoring or experimental recording. Quantification commonly involves manual pellet-weighing; however, this can physically disturb animals and cannot continuously assess both the amount and pattern of feeding. Improved means of food-intake measurement have been developed yet are often costly and incompatible with cage configurations. We therefore developed and validated the SnackerTracker—a cost-effective, open-source, and user-friendly measurement system which continuously records food-intake, food-seeking activity, and ambient light conditions in the home-cages of small laboratory animals.

EXPANDED TECHNICAL DETAILS

Diet Intelligence & Proximity Sensing

SnackerTracker is a humorous yet functional health-tech project that monitors how many times you open your snack cupboard.

  • Detection Method: Uses a Magnetic Reed Switch or a Limit Switch mounted on the cupboard door. Each "Open" event is recorded in the Arduino's non-volatile memory (EEPROM).
  • Interactive Feedback: Includes an OLED display that shows a "Daily Snack Count" and a Piezo Buzzer that plays a "Shaming" sound if you open the cupboard too many times in an hour.

Connectivity & Data

  • Arduino IoT Cloud: The snacking events are pushed to the cloud via WiFi.
  • MATLAB Integration: The historical data can be pulled into MATLAB for statistical analysis, allowing users to visualize their eating habits over weeks or months and correlate them with stress or time-of-day.
