@zboblamont I have the 2.0 as well.

RE: Round water tank level sensor
@Boots33 Sorry mate I have kind of taken over your thread! The project looks great. I might have to try the same sensor as you.

RE: Round water tank level sensor
@zboblamont I got mine to work by following the instructions from this guy. I also found the following drawing. . So my therory is if you change the variable inductor. You should be able to narrow the beam..... just a therory. If someone wants to try it... im happy to hear the results.

RE: Round water tank level sensor
@zboblamont I don't have a problem with my sensor. It works perfectly. It just casts a really wide beam. I'm estimating around 60 degrees!!! Has anyone tried changing the variable inductor on the unit to see if the beam can be narrowed?? Or does anyone have a schematic of the unit, as I have a friend who is an electrical engineer and might be able to help?

RE: Hardware design for 3.3V ProMini and 5v sensor
@zboblamont Thanks for the advice. I have been looking for a circuit diagram of the sensor to determine how adjusting it could change the beam. I would love if the beam was not as wide.

@zboblamont Thanks! What is it used for on the sensor?

@esawyja in the top photo, what is the component in the top left hand side? Is it a variable resistor??

RE: Round water tank level sensor
@Boots33, the readings I am getting are consistent..... they are just consistently wrong. I am going to try and install the sensor in a tube and see if that helps.
Fingers crossed! -
RE: Round water tank level sensor
Hi there. I am currently making the exact same project using a RPi3 and a JSN-SR04T ultrasonic sensor. My tank is 2 meters tall and are currently having issues with the sensor giving echos off the side of the tank. Did you have any issues like this? Im a SE Qlder as well.
