DFRobot Gravity - analog signal isolator

The module prevents the operation interference of the sensors through the insulation of the analog signal and providing an isolated power for sensors. Always during the measurement of the sensors prevent other sensors, for example, PH sensors affects the conductivity sensor. The solution is to isolate the power supply. After placing them in the same container and divide the same voltage, then their values will not be disrupted.

The module is powered with 5V voltage and is compatible with the 3-pin Gravity interface. It works in the Plug-and-Play technology with no soldering needed. It is compatible with most of the analog sensors.

Note:

1. The module must be powered with 5 V
2. Module, during operation consumes a lot of power, up to 170 mA, it is better to use an external power source
3. The sensor and the microcontroller (e.g. Arduino) are insulated, do not connect them together
4. The module can become hot during operation
