Hi yall, I have ZERO knowledge of coding, and i'm unfamiliar with Arduinos. I have to do a project for school were I will be constructing a motion activated pet feeder! I'm, looking for a motion sensor that will activated when the pet is in front of it. The motion sensor will active a lid covering…

Do you need a motion sensor, or perhaps a proximity sensor that will only trigger at a short range.

I would use a breakbeam detector like this. Will work with any color pet, white, black, or spotted. [image] IR Break Beam Sensor with Premium Wire Header Ends - 5mm LEDs Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends ou…

If you are specifically instructed to use a motion sensor I'd suggest the popular and cheap HC-SR501. But if your brief is more flexible then consider a simple microswitch-based approach. Perhaps a lightweight plastic board, levered to activate the switch when the pet steps on it.

Start by better defining your problem. A pet can range from an ant to an elephant, and that will affect your choice of sensor. Are you feeding your pet liquids, solids, or something else? How big is the lid? What will drive it? What will power the system? Where will it be located, and what are the a…

A PIR sensor will only activate when the pet is moving. And a PIR is usually way too sensitive (several metres). I think a proximity sensor (IR distance sensor) would be more suited. See this page. A simple platform/switch or beambreak, as suggested by others, could be easier if you're a beginne…

These Infrared proximity sensors are ideal for detecting the presence of a pet at short range. The short range digital sensors, like this one may the best choice, but the analog ones give you actual distance measurements. [image] Pololu - Sharp Distance Sensors Sharp distance sensors a…

Sounds like we're doing a similar project!! I'll have to revisit this. :smiley:
