HX711 Digital Load Cell Weight Sensor AD Converter Breakout Module +5KG Portable Electronic Kitchen Scale Module for Arduino Scale

Note:
if you use your own development board connect the test is not data, Please check the sensor signal line is occupied by other sensors on the development board.
if yes you change the IO port connection will be OK.
Be sure not to directly press on the white cover to prevent damage to the sensor.

Features:  
Two selectable differential input channels. 
On-chip active low noise PGA with selectable gain of 32, 64 and 128. 
On-chip power supply regulator for load-cell and ADC analog power supply.
