Assemble the depth sensor by adding the o-rings, and the connective wires in the order pictured, leaving the nut ring to the side

Note that the connective wires connect the depth sensor to the sensor node board. Remember, red wire is responsible for power, black is for ground, and white is for data

Place the depth sensor through the larger hole, and secure it firmly by tightening the nut ring

Make sure the nut ring is tightened securely as it will keep the enclosure water-tight
