Gravity: Analog Signal Isolator is a module that prevents electrical interference between sensors. In many cases, to ensure reliable operation of the sensors, isolation of the sensors in the device is required, because they can interfere with each other and will not perform correct measurements. The insulating module allows to separate the sensors in the device and increase the stability and reliability of operation. The module has a built-in 5V power supply, so you do not need to connect an external, additional power source for the sensor. The module has been equipped with a Gravity connector allowing easy connection of sensors to the module. The tile can be used, for example, in a multi-parameter water quality monitoring system.

In order for the module to work properly, it should be noted that:

  • module power supply should be stable to achieve stable readings
  • the current consumed by the sensors should not exceed 170 mA
  • do not short-circuit the mass field on the sensor side and the MCU module (they are isolated)
  • it is necessary to ensure heat dissipation from the module, because it can give off large amounts of heat
