Gravity: Analog Signal Isolator Module

For Makers who enjoy keeping beautiful pet fish or building a hydroponics farm, the healthier your water is kept the better. The chemistry of water has a large effect on plants and sea life living inside it, and often a slight imbalance will have dire consequences to your homemade ecosystem. Makers are fortunate to have access to quality sensor modules that measure the pH levels or conductivity within water. With this information, you can keep your water healthy and safe for your fishy friends. But a problem arises if you need to use more than one sensor within the same water source. Since water is extremely accepting of electronic current, the ambient currents from your many sensors with confuse each other’s readings and produce false results. To fix this, Makers must use a level converter like this Gravity Analog Signal Isolator Module.

Connecting this Gravity Analog Signal Isolator Module between the sensor and your MCU, you are able to completely isolate the sensor’s current signal and prevent electrical interference between sensors. You will always need one less Analog Signal Isolator than the number of sensors you have so that every signal is isolated and readable by the same MCU. The Gravity Analog Signal provides onboard 5V isolation power and 3-pin analog compatible connectors for most DFRobot sensors. These features allow you to plug and play with your new Gravity Analog Signal Isolator Module and get back to keeping your water safe.

Beyond preventing interference within your multi-parameter water monitoring system, the Gravity Analog Signal Isolator could have varied applications where electrical isolation is required. Our range of DFRobot sensor modules help countless Makers create their smart DIY projects. If you are looking for a reliable solution, these handy Gravity Analog Signal Isolator Modules will stabilise your sensors by isolating its signal and power.
