Product overview
The Whadda electronic scale load cell sensor package combines both an accurate load cell rated up to
20 kg, and a sensitive A/D converter board that easily interfaces with a large variety of microcontrollers
(such as an Arduino® compatible board).
In order to get accurate readings, the fixed side of the load cell should be mounted to a fixed, secure
part. It is recommended to also mount a sturdy measuring surface where the weights can be placed
upon to the measuring side of the load cell.
