Water & Liquid Sensors

SKU: LB-LR0040 | Brand: Little Bird

This versatile soil moisture sensor is designed for easy integration with both Arduino and Raspberry Pi projects, making it a great choice for hobbyists and developers alike. It features both analog and adjustable ...

SKU: DF-SEN0257 | Brand: DFRobot

The Gravity Analog Water Pressure Sensor measures water or gas pressure and outputs a linear 0.5–4.5 V analogue signal proportional to the applied pressure (0–1.6 MPa). Using the DFRobot Gravity 3-pin interface, it co...

SKU: DF-SEN0114 | Brand: DFRobot

A resistive soil moisture sensor that reads the water content of surrounding soil by measuring electrical resistance between its two probes. Wetter soil conducts more easily (lower resistance), while dry soil conducts...

SKU: DF-KIT0139 | Brand: DFRobot

This throw-in type liquid level transmitter adopts high-performance pressure sensing chip, with advanced circuit processing and temperature compensation technology. The level transmitter receives different pressures a...

SKU: SF-SEN-13637 | Brand: SparkFun

A simple breakout board for measuring moisture in soil and similar materials. The two large exposed pads act as probes — functioning as a variable resistor where higher moisture means better conductivity, lower resist...

SKU: EF-EF04024 | Brand: ElecFreaks

This is a Rain/steam sensor from ElecFreaks. This steam sensor can be connected to the Arduino IO Expansion shield directly. The output voltage will increase when the humidity of the sensor surface goes up.You even co...

SKU: SF-SEN-13322 | Brand: SparkFun

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probe...

SKU: DF-SEN0223 | Brand: DFRobot

The Gravity Conductivity Sensor Switch module can be used to detect if an object has electrical conductivity. Its maximum detection value is 10MΩ. It can detect not only coins, wires, metal and other good conducto...

SKU: DF-SEN0121 | Brand: DFRobot

This is a steam(water)sensor from DFRobot. This steam sensor can be connected to the Arduino IO Expansion shield directly. The output voltage will increase when the humidity of the sensor surface goes up. Notic...

SKU: AF-464 | Brand: Adafruit

The eTape Liquid Level Sensor is a solid-state resistive sensor that measures fluid level without mechanical floats. As the liquid level rises, the hydrostatic pressure compresses the sensor envelope, decreasing its r...
