This is a placeholder topic for “Grove - Water Level Sensor (10cm) for Arduino” comments.
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…

Additionally, if there is a way to make this shorter that would be great
Hi James,
There’s a few different means to water proof electronics. There are some aerosol lacquers about that offer great protection from water for electronics. I’ve also seen hot glue and silicon solutions used too.
While there should be nothing stopping you from trimming the end off the board to make it shorter you will damage the coating on the PCB to prevent corrosion. I’m not sure if it will have an impact on performance but assuming not you can subtract however much you cut off the board from your reading to zero it.

How can I connect this to an Arduino, the example code on the product does not work. I don’t want to use a seperate ‘host board’, I wish to just connect the SCL and SDA to the Arduino.
Hi @J.a.m.e.s,
Would you be able to share some more about how you have this set up?
I would hope that connecting:
- Grove sensor to Arduino
- Ground (1) to GND
- VCC (2) to 5V
- SDA (3) to SDA
- SCL (4) to SCL
The Arduino side of this connection may be different depending on your board. Would you be able to share what specific board model you are using so we can continue troubleshooting from there?
Hope this helps!
