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 I am a proud Patreon of @GreatScott!, @ElectroBOOM , @Electronoobs , @EEVblog , and others.
