Sensors / Liquid / Flow

The spice liquid must flow!

Electronics and water don't usually mix - which is why liquid level sensing projects can be a little challenging. But we have a number of solutions that don't require the Gom Jabbar test. Check out our options of liquid solenoid valves, which are great for robotic gardening, aquarium, pool projects, or maybe terra-forming planets (still in R&D). Or if you need to measure liquid levels, we have eTapes of varying lengths, including ones with protective plastic casing.
