Weight Sensor Module is based on HX711,which is a precision 24-bit analog-to-digital convertor

designed for weigh scale and industrial control applications to interface directl with a bridgesensor!"o#pared with other chips, HX711 not onl has a few basic function,also contains high

integration,fast response,i##unit,and other features!$he chip lowedrs the cost of the electronic

scale,at the sa#e ti#e,i#proving the perfor#ance and reliabilit!

$he input interface of this weight sensor #odule is used sensor interface,which is co#patible

with %rduino &'( port!$he output adopts co#pact ter#inal that #a)es weight sensor #odule

easier to connect the weight sensor!&t*s the best choose for electronic enthusiast to do so#e tin

ho#e scale!

$he weight sensor #odule can be co#bined with weight sensor on the #ar)et! We also help outo pic) a s#all range of weight sensor!
