Gravity: Analog Signal Isolator _ARD_SHIELD_PROTO just what you need orIn many cases, electrical isolation is required to ensure the reliable operation of sensors. Some sensors, such as pH sensors and conductivity sensors, will interfere with each other and do not measure properly in the same container when they connect to the same power. To ensure stable and reliable operation of the sensors with no interference, it is necessary to isolate the signal and the power. The Gravity: Analog Signal Isolator is efficient in
