Works for raspberry pi
The module uses 24 high-precision A / D converter chip hx711, is designed for high-precision electronic scale and design, with two analog input channels, the internal programmable gain amplifier integrated multiplier 128.
The input circuit can be configured to provide a bridge voltage electrical bridge (such as pressure, weight) sensor model is an ideal high-precision, low-cost sampling front-end module
Two selectable differential input channels

Note:
Please allow 1-3mm slight deviation due to manual measurement. Thank you!
One end of the sensor is fixed by the screw hole, the other end is kept in a floating state, and the gravity is applied in the direction indicated by the label.
Special attention must be paid not to directly press the white rubber part to avoid damage to the sensor.
