What is Arduino
Arduino® is an open-source prototyping platform based on easy-to-use
hardware and software.
Arduino® boards are able to read inputs – light-on sensor, a finger on a
button or a Twitter message – and turn it into an output – activating of a
motor, turning on an LED, publishing something online. You can tell your board
what to do by sending a set of instructions to the microcontroller on the
board. To do so, you use the Arduino programming language (based on Wiring)
and the Arduino® software IDE (based on Processing). Additional
shields/modules/components are required for reading a twitter message or
publishing online. Surf to www.arduino.cc for more
information.
Product overview
This practical module can sense the presence of water. It is contactless
because there is no sensing element that makes physical contact with the
water. The sensor is even able to detect the presence of water through small
thicknesses of plastic, glass, ceramic, and other non-metallic materials.
The sensor features a built-in red indicator LED that lights up when water is
detected and the detection signal will output a high signal when water is
present. The polarity of the detection signal can be changed by grounding the
black wire, which will change the detection signal type to an active low
signal. The sensor’s sensitivity can be adjusted by opening the top cover and
turning the blue potentiometer.
