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.

Plastic Water Solenoid Valve - 12V - 1/2" Nominal
Product ID: 997Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening project. There are two 1/2" (Nominal non-taped National Pipe) outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can push through. The valve has a gasket arrangement inside, so there...$6.95In stock -
Simple Water Detection Sensor with Digital Output
Product ID: 4965Keep wet things wet and dry things dry by detecting when the dry things get wet by accident! This palm-sized cherry-red water sensor is simple and easy to implement in your wet-dry-sensing project. Usage is very simple: connect the minus (-) pin to ground, connect the plus (+) pin to 3 to 5V DC and then the output signal pin (S) goes to your microcontroller. The...$1.95In stock -
Adafruit Simple Soil Moisture Sensor - For micro:bit, and more
Product ID: 6362Perfect for educational uses, the Adafruit Simple Soil Moisture Sensor is low cost, and easy to use. This is a simple resistive style moisture sensor, where there's two prongs and the sensor measures the conductivity between the two. We gold-plated the prongs so reduce risk of oxidation - if you see build-up on the prongs, clean them off with a dish-scrubber to keep...$3.00In stock -
Clear Turbine Water Flow Sensor with 3-pin JST
Product ID: 5066Measure liquid/water flow for your solar, computer cooling, or gardening project using this handy basic flow meter featuring a fully clear plastic body. This sensor sits in line with your water line and uses a pinwheel sensor to measure how much liquid has moved through it. The pinwheel has a little magnet attached, and there's a hall effect magnetic sensor on the...$6.5012 in stock -
12" eTape Liquid Level Sensor + extras
Product ID: 464The eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. The eTape sensor's envelope is compressed by the hydrostatic pressure of the fluid in which it is immersed. This results in a change in resistance that...$39.9528 in stock -
Brass Liquid Solenoid Valve - 12V - 1/2 Inch G / BSP Thread
Product ID: 996Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening, aquarium, or pool project. There are two 1/2" (British Standard Pipe / German Thread) outlets. Normally, the valve is closed. When 12VDC is applied to the two terminals, the valve opens and water can flow. Unlike the plastic solenoid valve,...$24.9594 in stock -
