Gravity Analog Signal Isolator Optocoupler

To ensure that sensors like pH sensors and conductivity sensors provide accurate measurements, it's crucial that they are electrically isolated. The Gravity: Analog Signal Isolator can prevent interference between sensors and has an integrated isolation voltage. This allows for easy plug-and-play without soldering and minimizes impacts on the measurements of the connected sensors. The Gravity: Analog Signal Isolator is useful in multi-parameter water quality monitoring systems that need to eliminate interference between water sensors. The product is compatible with most analog sensors from DFRobot and meets various requirements in situations that demand electrical isolation.
