Water & Liquid Sensors

SKU: DF-SEN0308 | Brand: DFRobot

The Gravity Analogue Waterproof Capacitive Soil Moisture Sensor from DFRobot measures soil moisture using capacitive sensing rather than resistive probes, offering significantly better corrosion resistance and longer ...

SKU: DF-SEN0205 | Brand: DFRobot

A photoelectric liquid level sensor that uses optical principles to detect the presence or absence of liquid. With no moving parts, it requires minimal calibration and offers high sensitivity and long service life. Th...

SKU: AF-4026 | Brand: Adafruit

The Adafruit STEMMA Soil Sensor uses capacitive measurement to detect soil moisture — a more durable approach than resistive sensors that corrode over time. With a single probe and no exposed metal, it avoids oxidatio...

SKU: DF-SEN0204 | Brand: DFRobot

A non-contact liquid level sensor that detects the presence of liquid through a container wall — no direct contact with the liquid required. Using advanced signal processing via the XKC-Y25-T12V chip, it works through...

SKU: EF-EF04097 | Brand: ElecFreaks

The Octopus Capacitive Soil Moisture Sensor uses capacitive sensing to detect soil moisture levels, avoiding the corrosion problems common with resistive sensors for a much longer service life. It outputs an analogue ...

SKU: DF-SEN0368 | Brand: DFRobot

A non-contact capacitive liquid level sensor that detects whether liquid is present inside a non-metallic container or pipe without direct contact with the fluid. It works by measuring changes in capacitance through t...

SKU: DF-SEN0193 | Brand: DFRobot

The Gravity Analogue Capacitive Soil Moisture Sensor measures soil moisture using capacitive sensing rather than resistive probes, providing significantly better corrosion resistance and longer service life. Made from...

SKU: DF-SEN0485 | Brand: DFRobot

This small 5V non-contact liquid level sensor with Gravity Interface is able to detect 0-100°C conductive liquid levels in non-metallic containers in sensing range of 3mm. Provided with digital quantity output(low), t...

SKU: AF-5587 | Brand: Adafruit

If you're like me and have trouble keeping your calatheas and pepperomias happy and not overwatering them to root rot ruin, why not take a gander at the Plant Monitor from Ada-friend Monk Makes. Its a super easy and f...

SKU: SF-SEN-15272 | Brand: SparkFun

If your plants could talk, would they call out "Water me, Seymour?" Unfortunately (or fortunately, perhaps) plants have yet to develop the ability to speak. But thanks to the SparkFun gator:soil micro:bit Accessory Bo...

SKU: DF-SEN0508 | Brand: DFRobot

This flexible capacitive liquid level sensor detects liquid through the wall of a non-conductive container, so it does not need to touch the liquid itself. It is designed for containers with a wall thickness of less t...

SKU: DF-SEN0716 | Brand: DFRobot

This industrial non-contact liquid level sensor uses capacitive sensing to detect liquid through non-metallic container walls, so it does not need to touch corrosive, viscous or contaminated liquids. It is suited to l...

SKU: DF-SEN0715 | Brand: DFRobot

This compact capacitive sensor detects the presence or level of liquid through non-metallic container walls, so it does not need to touch the liquid. That helps avoid corrosion, contamination and media adhesion when m...
