For the Bay of Plenty Science Fair, the 14-year-old Bethlehem College student designed and built ‘Gran Check’, a Raspberry Pi-powered monitor that uses a PIR sensor to recognise his gran’s movement as she feeds her dogs, taking a photograph every morning to email back to his mother.
The Gran Check lives within a wooden box, installed beside his grandmother’s dogs’ food. He knew it was the best location, since the dogs would never allow her to go a day without feeding them. For added peace of mind, James built the device to be self-sufficient, ensuring she’d never have to operate it herself.
James noted his grandmother’s independent nature, understanding that constant ‘check in’ calls from the family would be unrealistic. The Gran Check removes all concern for her welfare, without constantly bugging her for updates.
