Gravity: Analog Signal Isolator

The Gravity: Analog Signal Isolator is an effective solution for eliminating electrical interference between sensors. It features an onboard 5V isolated power supply, capable of directly powering connected sensors—eliminating the need for an external power source. This makes the module both convenient and practical for various applications.

Designed with ease of use in mind, the module includes specially designed connectors compatible with DFRobot 3-pin analog sensors, allowing for plug-and-play functionality without the need for soldering. It maintains a 1:1 analog signal transmission ratio, ensuring minimal impact on sensor output signals when integrated into a circuit. Notably, no changes to the microcontroller's code are required when adding this module.

This analog signal isolator is particularly useful in setups where sensor interference is a concern—such as multi-parameter water quality monitoring systems—by providing reliable signal isolation between multiple analog sensors.

Gravity: Analog Signal Isolator Interface

This product is almost compatible with all analog sensors produced by DFRobot. It could satisfy varied demands in situations that require electrical isolation.

The MCU terminal (non-isolation terminal) should be provided with precise voltage of 5.0±0.1V. The higher the precision of input voltage, the higher the precision of analog output signal.
This module consumes relatively large current during operation, so you'd better to provide external power supply to Arduino board to guarantee enough power and voltage precision.
Please pay attention to the operating current of your sensor or module, the maximum output current from SEN terminal is 170mA.
The GND of the MCU terminal(non-isolation terminal) and the GND of SEN terminal (isolation terminal) are isolated from each other. Do not short circuit them.
It is normal for the isolator generates heat while working.
