HX711 Weighing Pressure Sensor Module amplifier is based on HX711, which consist of an amplifier and a precision 24-bit analog-to-digital convertor designed for weigh scale and industrial control applications to interface directly with a bridge sensor. Compared with other chips, HX711 not only has a few basic function, also contains high integration, fast response, immunity, and other features. The chip lowed the cost of the electronic scale, at the same time, improving the performance and reliability. The input interface of this weight sensor module is used sensor interface, which is compatible with open source board I/O ports. The output adopts compact terminal that makes weight sensor module easier to connect the weight sensor. It's the best choose for electronic enthusiast to do some tiny home scale.
This HX711 Weighing Pressure Sensor 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 as pressure, weighing sensor mode), is of high precision, low cost is an ideal sampling front-end module.
