I am a complete beginner trying my hand at a home automation project.
Part of my setup includes using an Arduino UNO REV3 (A000066), and connecting two CQRobot Ocean Non-Contact Water/Liquid Level Sensors (CQRSENYW001).
There is great documentation for the sensor:
http://www.cqrobot.wiki/index.php/Non-Contact_Water/Liquid_Level_Sensor_SKU:_CQRSENYW001
And setting up one sensor is a breeze (see setup in image below):
- Red Wire to 5V
- Black Wire to GND
- Green Wire (Output) to 7
Since there is only one 5V on the Arduino (and since the project could expand), it sounds like I need to use a breadboard to allow for expansion.
I used the following video to connect the Arduino to the breadboard for power:

Now to connect the two sensors, do I just need to put the Black and Red Dupont Wires from the sensors anywhere in the - and + columns on the breadboard and connect the green wires back to the Arduino for the output in 6 and 7?
In other words, does the setup look correct below?
I have noticed that doing this seems to work for the most part (there is power) for the sensor, but I just want to make sure I am doing this right. Thanks!
