Thanks for the reply. I tried following the steps as you suggested above, i noticed when i uploaded the address change example onto the arduino board and connected the sensors it ask for new address i input 1 for the first sensor but the address of the sensor still said 0. I continued with the other sensors as you had suggested, but at the end when i ran the sample code you sent i could not get the results. I don’t know exactly what i am doing wrong.
So i went ahead to measure the input voltage at the sensors but noticed it was really low so i am guessing thats where the issue is. Please can you provide me with a diagram on how to connect the few sensors to gather?
