I bought this for a reefpi project and followed the instructions from Adafruit. For an automatic top-off system (ATO) for my reef tank, it performs as expected.
For my setup, this is ideal. This is being used as a minimum water level sensor in conjunction with a maximum water level sensor. If the minimum sensor is triggered, the water will turn on until it reaches the maximum setting. The cable's only disadvantage is its length. It's a quick read. I'll have to make an extender at some point because it's so short. However, it performs admirably as advertised.
pi ATO. The item was bought to keep track of the water level in a saltwater aquarium. I decided to follow the reef. This sensor was instantly recognized and worked flawlessly after following the pi tutorial. This sensor is not waterproof! br>br>It is important to note that this sensor is not waterproof! It has two sides, one wet and one dry, so use caution when installing it. br>br>The vendor is extremely responsive and stands behind their product; I will be purchasing more from them in the future.
The unit performed admirably in two of my Arduino projects, detecting suto fill water in awuariums and rain detection for an avremote observatory.
I was able to measure water from about an inch to over a foot in depth using this device, which interfaces easily with an Arduino.
This is a fantastic product that does exactly what it says on the tin. br>br>When the time comes, I will definitely buy again. br>br>Many thanks for the excellent service and quick turnaround.
Arduino projects are supported.
Love it. I used it to change the water in my aquarium in an arduino project and it worked flawlessly.
