Step 1: The sensor

The sensor mesure the time it took to an ultrasound to get back to it.

Step 2: Create the base

First, cut a 3 inches hole in the thicker 4”X6” piece of wood. Stick the pieces of wood together.

Step 3: Prepare the base for the sensor.

Drill two 3/4” hole in the center of the 3” hole. The distance between them is 1”. Add 3 screw to hold the pipe.

Step 4: Add the sensor

Mount the sensor on 2 spacer to keep the sensor level. Stick the sensor to the spacer with hot glue.

Step 5:
