Gravity Analog Signal Isolator Optocoupler

To ensure that sensors such as pH sensors and conductivity sensors provide accurate measurements, it is important that they are electrically isolated. The Gravity: Analog Signal Isolator can prevent interference between the sensors and features an integrated isolation voltage. This allows for easy plug-and-play without soldering and minimizes the impact on the measurements of the connected sensors. The Gravity: Analog Signal Isolator is useful in multiparameter water quality monitoring systems that need to prevent interference between water sensors. The product is compatible with most analog sensors from DFRobot and meets various requirements in situations requiring electrical isolation.
