Product details

To ensure that sensors such as pH sensors and conductivity sensors provide correct measurements, it is important that they are electrically isolated. The Gravity: Analogue Signal Isolator can prevent interference between sensors and has an integrated isolation voltage. This allows for easy plug-and-play without soldering and minimises the impact on the readings of the connected sensors. The Gravity: Analogue Signal Isolator is useful in multi-parameter water quality monitoring systems that need to prevent interference between water sensors. The product is compatible with most DFRobot analogue sensors and meets various requirements in situations that require electrical isolation.
