I have used four half bridge load sensors and connected them in a bridge. I have fed the output of the sensors to the ADC (ADS1230) which is a 20 bit analog to digital converter.I have used ATMEGA16 microcontroller that takes the input from the ADC and displays to the LCD. After observing the values in the LCD, I found that the output of the sensor got highly fluctuated. What might be the solution of this problem.![HALF BRIDGE LOAD SENSOR][1]
