Smart Weighing Scale

Looking to build a simple smart weighing scale. Features required are -

- Device should be small - shape & size of a coaster (circular, but not very thick)

- Should be cheap to make & easy to replicate - prototype can be around $10 - $15, but if it needs to be mass manufactured, we would need to do it around $3 - $4

- Device should be battery powered (flexible on battery capacity, based on cost) - ideally rechargeable battery

- Maximum weight expected would be 1 - 2kg

- 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)

Kĩ năng: Internet of Things (IoT), Không dây, Arduino, Raspberry Pi, Điện tử

Hi I have worked on weighing machine using arduino and esp32. I think any load cell with amplier would work which has accuracy around 1g. I want to know more about your system. Can we discuss?
