The sensor has to be submerged in the water for this to work properly. Arduino leak sensors only have three pins to connect, making them easy to wire up with your Arduino board and pair with other ...

Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

We don’t think we’d want to trust our fire safety to a robot carrying a few ounces of water, but as a demonstration or science project, [Tinker Guru’s] firefighting robot was an e… ...
