Gravity: Digital I2C Signal Isolator 數字I2C 信號隔離器 DFRobot原廠

Digital I2C Signal Isolator 數字信號隔離器能夠隔離I2C數字信號並為傳感器模塊提供隔離電源,有效防止傳感器模塊之間的相互干擾。該數字信號隔離器可用於多參數水質檢測系統,以防止水質傳感器相互干擾。

在許多情況下,存在干擾源。例如,魚缸中的運行泵將向水中釋放信號,這會干擾魚缸中的傳感器。在這種情況下,需要電隔離以確保傳感器的穩定操作。一些傳感器,如pH傳感器和電導率傳感器,在同一容器中共用相同的電源和測量值,會相互干擾,無法正常工作。為了確保傳感器模塊的穩定運行,必須隔離信號和電源。

在模擬信號隔離器之後,我們推出了這種數字信號隔離器,專門隔離I2C數字信號。此外,板載5V隔離電源芯片可直接為傳感器模塊供電,無需額外電源。本產品專為 DFRobot I2C 連接器傳感器或模塊而設計,即插即用,無需焊接。將其連接到電路中進行電氣隔離,控制板上的傳感器模塊代碼無需修改,簡單方便。

Gravity: Digital I2C Signal Isolator

Gravity: Digital Signal Isolator is capable of isolating I2C digital signal and providing isolated power to the sensor module, effectively preventing mutual interference between the sensor modules. This digital signal isolator can be used for multi-parameter water quality detection systems to prevent water quality sensors from interfering with each other.

In many cases, interference sources are existing. For example, a running pump in a fish tank will release signals into the water, which interferes the sensors in the fish tank. In this case, electrical isolation is needed to ensure the stable operation of the sensors. Some sensors, such as pH sensors and electrical conductivity sensors, which share the same power source and measure in the same container, will interfere with each other and do not work properly. In order to ensure stable operation of the sensor modules, it is necessary to isolate the signal and the power.

After the analog signal isolator, we launched this digital signal isolator which specifically isolates the I2C digital signal. What’s more, the on-board 5V isolation power chip can directly supply the sensor module, without additional power. This product is designed specifically for DFRobot I2C connector sensor or modules, plug and play, no welding. Connect it into your circuit to get electrical isolation, and the code of sensor module in control board does not need to be modified, which is simple and convenient.

Note:

1. Please pay attention to the operating current of your sensor or module, the maximum output current from Module side is 150mA.
2. All pins on the Module side (isolation side) are isolated from all pins on the Controller side (non-isolation side). Do not short-circuit them.
3. It is normal for the isolator generates heat while working.

FEATURES

  1. Onboard 5V 0.75W isolation power chip, no additional power needed, simple and convenient
  2. Almost compatible with all DFRobot I2C connector sensors or modules, plug and play, no welding
