US$7.73 US$7.76

Q: This sensor uses I2C , that means 4 wires are required. In the picture of the wires I only see 3 wires. I think this should be 4 wires. Am I correct?

Praxig Two ports are power input, and the other two are signal input. I think this cable (3pin) is not connected to the port on the circuit board.
