There are many sensors to be measodured the outside word envirment,the sensor must be amplified,filter to the standard current or voltage, that can be connected to the standard A/D modules, how to reduce the interference, please reference the following items: 1 use the shielded cable,and connect the shield cable at the sensor side. 2 leave the cable far away with the high current cable 3 do not ground the signal to both side. 4 avoid destroy the cable.
