receive signal from non-contact fluid-level sensor via bluetooth on iphone

(Read 56 times)
 need help to know if its possible to receive signal from surface mount sensors that detect fluid level on a tank using arduino+HM-10 or esp32
need data sent to iphone.
signal sent via bluetooth since distance is only one meter from sensors to iphone
need data from 3 sensors (variable height on tank to sense fluid or not
is it complicated sketch?
thanks



To detect fluid height usually we use something that floats... What sensor you want to use?
