10 Fluid Level Sensors and how to use them (Arduino, ESP32, ESP8266)



Measuring levels of liquids is a common problem. Where I live, it is probably more the water level of the coffee machine, in rural areas the level of a water tank, and in the industry the level of chemical substances. There are many different ways to get this job done. If you stick around, I will show you ten different sensors and, as usual, we will learn some new tricks.
– Sensors that react on fluid level thresholds
– Sensors that measure the fluid level
– Sensors that have to be mounted inside and sensors that are mounted outside the tanks
– Sensors for the top and for the bottom of the tanks
– And, as usual, you get some background info on the sensor interfaces
