  • Garden Soil Moisture Humidity Sensor For Arduino, PIC,AVR ( Copy ) ()

    This moisture sensor can read the amount of moisture present in the soil surrounding it. It's a low tech sensor, but ideal for monitoring an urban garden, or your pet plant's water level. This is a must have tool for a connected garden!

    This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance).

    It will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.

  • ICS43432 I2S Digital Microphone ()
    • This is a small (0.4 in x 0.3 in) breakout board for TDK's (Invensense's) ICS43434 bottom-ported, digital microphone that outputs I2S audio as a stream of 24-bit serial words that can be directly read by any microcontroller with an I2S port. No CODEC is required to decode the audio data!

      The ICS43434 has the same low noise and high sensitivity as the ICS43432 but cuts the power usage from 1.1 mA in normal mode to ~500 uA and adds a low-power mode which uses just 230 uA. That's right, the ICS43434 uses only 20% of the power of the ICS43432!

      The pinout is straightforward. The microphones are NOT 5 V tolerant so apply no more than 3.6 V to 3V3 on the board.

      On the Teensy 3.2, CLK connects to Teensy pin 9 (BCLK), WS connects to Teensy pin 23 (LRCLK), and pin 13 is the serial data out.

  • GY-4466 Professional MAX4466 High Precision Electret Microphone Amplifier with Adjustable Gain for Arduino ()
    • Features:
      Add an ear to your project with this well-designed electret microphone amplifier.
      This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task.
      The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried!
      This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain.
      You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC.
      The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp!

      Material: electronic element
      Color: purple

  • Ultrasonic Distance Sensor ()

    ultrasonic sensor provides an easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects.

    Interfacing to a microcontroller is a snap. A single I/O pin is used to trigger an ultrasonic burst (well above human hearing) and then "listen" for the echo return pulse. The sensor measures the time required for the echo return, and returns this value to the microcontroller as a variable-width pulse via the same I/O pin.

    Application Ideas:

    • Security systems
    • Interactive animated exhibits
    • Parking assistant systems
    • Robotic navigation

  • VL53L0X Time-of-Flight (ToF) Laser Ranging Sensor Breakout 940nm GY-VL53L0XV2 Laser Distance Module I2C IIC 3.3V/5V ()
    The VL53L0X from ST Microelectronics is a time-of-flight ranging system integrated into a compact module. This board is a carrier for the VL53L0X, so we recommend careful reading of the VL53L0X datasheet (1MB pdf) before using this product. 

    The VL53L0 uses ST's FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object's reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor's accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.) 

    Ranging measurements are available through the sensor's I⊃2;C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output. 

    The VL53L0X is a great IC, but its small, leadless, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for microcontrollers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.

    2, the main parameters are as follows: 
     
    A, dark current, the dark resistance: sensitive resistance at a certain applied voltage, when no light irradiation, when the current flowing is called dark current. The applied voltage and the dark current of the dark resistance than known; 
     
    B, Sensitivity: Sensitivity refers to the resistance value of the photosensitive resistance against light irradiation (dark resistance) the relative change in the value of the resistance value of the light irradiation (light resistance). 
     
    C, volt-ampere characteristic curve. Volt-ampere characteristic curve used to describe the relationship between the applied voltage and the photoresistor photocurrent, for the photosensitive device, its photocurrent with the applied voltage increases. 
     
    D, the temperature coefficient. Photoelectric effect photoresistance influenced by temperature, partial photosensitive resistance at low temperature sensitive photoelectric higher, and sensitivity at high temperatures are lower. 
     
    E, rated power. The rated power is used to refer to certain lines in the photosensitive resistor being allowed to consume power when the temperature rises, the power consumption is reduced.
