The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

If you’re interested in building your own laser sky effect generator, you’ll need a few key components: an Arduino Uno, a laser module, mirrors, motors to spin the mirrors, a photoresistor, an ...

The Arduino Sensor Kit comes as a standalone kit for only €23.00 or $23.00, or can be purchased with the Arduino UNO Rev3 board as a great value bundle for €38.70 or $38.70.

Teledyne e2v has announced a family of CMOS image sensors for 3D laser triangulation – for use in applications such as distance measurement, profile measurement and high resolution physical inspection ...
