- This module uses 24 high precision A/D converter chip HX711. It is a specially designed for the high precision electronic scale design with two analog input channel the
- Internal integration of 128 times the programmable gain amplifier. The input circuit can be configured to provide a bridge type pressure bridge (such aspressure weighing sensor mode)is of high precision low cost is an ideal sampling front-end module.
- Four leads, easy to use
- 5-10V drive voltage applied, the force is directly output as a voltage change signal.
