  • Dust Sensor - Sharp GP2Y1010AU0F
    GP2Y1010AU0F is a dust sensor by optical sensing system. An infrared emitting diode (IRED) and an phototran-sistor are diagonally arranged into this device. It detects the reflected light of dust in air. Especially, it is effective to detect very fine particle like the cigarette smoke. In addition, it can distinguish smoke from house dust by pulse pattern of output voltage. Parameter: Compact, thin package (46.0 × 30.0 × 17.6 mm) Low consumption current (Icc: MAX. 20 mA) The presence of dust can be detected by the photom..

  • Grove - Water Sensor
    This water sensor module is part of the Twig system. This sensor works by having a series of exposed traces connected to ground and interlaced between the grounded traces are the sens traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace. Believe it or not this circuit will work with the digital I/O pins of your Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.   Features Grove compatible interface Low power consumption 2.0cm x 2.0cm twig module High sensitivity Applications Ideas ..

  • Moisture Sensor
    Description: This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module plant waterer device, so that the plants in your garden without people to manage.   Test procedure First , we use 5v voltage to the  Soil moisture sensor on pin VCC and GND,the green Power Indicator will be turned on, then we plug it into a small cup, which already fulled with dry soil, and then we pour some water into it,you will find the red led light is on now,if it change back to dry, it will off. Meanwhile,   and if you test the voltage on the pin of DO,  it will change from 4.5v to about 0.15volt, so it is working now, even you can use it to make a automatic equipment to water your flower!     Fe..
