Smart Weighing Scale - Small Size
Оплачивается при доставке
I am looking to build a simple prototype for a smart weighing scale, that is compact in size.
Features required are -
- Device should be small & circular in shape (shape & size of a coaster) - approx 10 cm in diameter and 0.8 cm in thickness)
- Should be cheap to make & easy to replicate. Prototype should not cost more than $10 - $15, but when mass manufactured, it should cost no more than $3 - $4
- The device should be battery powered (flexible on battery capacity, based on cost). Battery should be rechargeable.
- Maximum weight that the device needs to handle is expected to be ~3kg
- Require precision of 1g
- Device should have a button, which when pressed sends the weight data
- Device sends data to a web API/ via Bluetooth (either is fine)
