He decided to replace this with a modern mass air flow (MAF) sensor instead, and documented the process online.

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 ...

Programmable-Air consists of a built-in high-pressure pump, vacuum pump, pneumatic valves, pressure sensor, and an Arduino Nano.

If you have allergies than you've likely considered picking up an air quality sensor for you house at some point. However, a good air quality monitor will run you upwards of $290.

Its developers explain : “With EasyPlug Air it’s almost too easy to create wireless Arduino projects. You simply pick a sensor, plug it into your receiver and that’s it.

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 ...
