Description
The Gravity: Analog Signal Isolator is an effective solution for combating electrical interference between sensors. It features an onboard 5V isolation power source that can directly power the sensor, making it a convenient and practical solution. The wires are equipped with a special connector designed for the DFRobot 3Pin analog sensor, allowing for easy plug-and-play use without the need for soldering. The analog signal transmission ratio is 1:1, minimizing the impact on the output signals of the sensors when integrated into the circuit. Additionally, there is no need to make changes to the code of the mainboard.
This analog signal isolator is ideal for use in a variety of applications, such as multi-parameter water quality monitoring systems where it is important to prevent interference between water sensors.
Gravity: Analog Signal Isolator Interface
-
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.
