  • DHT11 Temperature and Humidity Sensor
    INTRODUCTION DFRobot's latest generation of digital Temperature and Humidity sensor is as powerful as it used to be but easier to use.  DHT11 has a full range temperature compensation, low power consumption, long term stability and calibrated digital signal. A high-performance 8-bit microcontroller is integrated in the sensor with calibration-coefficient saved in OTP memory to provide accurate temperature readings. With the new 3 pin connector that includes several soldering pads and a sturdy casing, plugging in and out the sensor is not going to be a problem anymore. The 3 pin connector is perfect to get it going fast, and extremelly easy to use with our 3 pin sockets expansion boards. Reliable and inexpensive with plenty of..
  • 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..
  • Dust Sensor DSM501A
    DSM501 series detect the level of indoor airborne dust, particles, and pollen, and ideal for use in stand-alone air cleaner or IAQ monitor. PWM output of the sensor can be directly connected to μ-com to control fan speed or ventilation and also to display the level of particles. Detectable size of particle is limited to minimum 0.7 μm, and the application for smoke or fire alarm is prohibited. Include: 1 x DSM501 1 x 5P Cabal     ..
  • Grove - Dust Sensor
    Grove - Dust Sensor Sensor is to create Digital (Lo Pulse) output to Particulate Matters (PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output is for PM whose size is around 1 micro meter or larger. We can use the sensor to detect the dust in clean room.    For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.   Features Grove compatible interface(extra wire with connecter)  Supply voltage range: 5V  Minimum detect particle: 1um  PWM output  Dimensions: 59(W)x45(H)..

  • 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..
