Hot Swappable, Dual I2C Isolators with Integrated DC-to-DC Converter. This product is designed specifically for DFRobot I2C connector sensor or modules, plug and play, no welding. SPI/Digital or I2C Module Isolator with Dual Adjustable 5V Regulators. What's more, the on-board 5V isolation power chip can directly supply the sensor module, without additional power. We are using clock stretching for I2C communications which gave us timing problems when the slave device was supposed to acknowledge a message. In order to ensure stable operation of the sensor modules, it is necessary to isolate the signal and the power.Īfter the analog signal isolator, we launched this digital signal isolator which specifically isolates the I2C digital signal. 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 this case, electrical isolation is needed to ensure the stable operation of the sensors. For example, a running pump in a fish tank will release signals into the water, which interferes the sensors in the fish tank. In many cases, interference sources are existing. This board features the ISO1540, a low-power, 2. This digital signal isolator can be used for multi-parameter water quality detection systems to prevent water quality sensors from interfering with each other. I2C Isolator Click is a compact add-on board that offers completely isolated bidirectional communication. 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.
