PRODUCT DETAILS

The Grove Water Level Sensor is a very accurate sensor that can be helpful in water level sensing applications. It is completely waterproof and uses capacitive pads to detect water levels up to 10cm.

Features

  • High measurement accuracy: Since the sensor is based on capacitive sensing, The measurement accuracy is up to ±5 mm.
  • Outstanding corrosion resistance: Inevitably, some liquids may be corrosive during use, and with the help of corrosion-resistant materials, the sensor can be used for a long time.
  • Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.

Description

The Grove Water Level Sensor is a very accurate sensor that can be helpful in water level sensing applications. It is completely waterproof and uses capacitive pads to detect water levels up to 10cm.

We used capacitive pads on the PCB of the module and did conformal coating over the PCB to make the sensor protect against moisture, dust, chemicals and high temperatures. We believe that this technique will allow you to make accurate water level measurements (±5mm accuracy) easily

Let’s look at the difference between few water level sensing methods.

Ultrasonic Distance Sensor Sensor based on Resistance Grove - Water Level Sensor
Principle Ultrasonic Waves Resistance Capacitance
Communication Interface Digital Analog I2C
Operating Voltage 3.3/5V 3.3/5V 3.3/5V
Waterproof No Yes Yes

Note

The blue oil layer on the surface of the module’s capacitance sensing area should be kept intact. When the oil layer is damaged and the test object is a conductive liquid, the test data may be abnormal.

Attention

When testing, the highest liquid level inserted should not exceed the white dividing line, otherwise it will cause a short circuit.

Applications

  • Tank overflow detection
  • Liquid level sensing applications

    Raspberry Version
    Can we use this product in raspberry pi 4 with grove base hat? I have a base hat and this sensor is perfect my project. Is there any way to make this sensor operate on rpi4?

    Good
    Works pretty nicely, except after power off.
    Can't take power off while in water - then reads 0.
    Seems as a capacitance based sensor, when powering up needs to baseline the capacitance - guessing on my part - that is needs to be out of the water. Once read a baseline capacitance, then it detects increase in capacitance, water crossing. If the baseline capacitiance could be read, and then programmed, maybe it could survive a power off. API isn't clear on how this might happen, as its for an LCD.
