Product description: Gravity - digital pressure sensor 1 kg (10 N) - HX711 - scale builder kit - DFRobot KIT0176
A set of self-assembly components that allow you to make an electronic scale. The kit contains a digital pressure sensor, in the form of a strain gauge bar, detecting pressure from 1 g to 1 kg (10 N). In addition, the manufacturer has also included a signal converter with a built-in HX711 chip. When assembled, the scale has dimensions of 120 x 100 x 30 mm.
This product is compatible with Arduino and Raspberry Pi!
Detailed user guide is available on manufacturer website - check it out!
