Design and build a wireless ultrasonic distance sensor that feeds to an app
Budget: $30 – $250 NZD
I am looking for someone to build me an ultrasonic distance sensor that is wireless. This needs to feed to an app to determine is an item is present or not.
The project will also need to be scalable - so it would need to be able to have up to possibly 20000 sensors feeding to the app.
