WWH-Analog Sound Sensor
Introduction
This is an updated version of the Analog Sound Sensor. Analog Sound Sensor is typically used in detecting the loudness in ambient, the Arduino can collect its output signal by imitating the input interface. You may use it to make some funny interactive works such as a voice operated switch.
As one of our new version of breakout boards, we have improved the analog sound sensor in below:
Wide voltage range from 3.3V to 5V
Standard assembling structure (two 3mm holes with multiple of 5cm as interval)
Easily recognitive interfaces of sensors ("A" for analog and "D" for digital)
Icons to simplely illustrate sensor function
High quality connector
Immersion gold surface
Notice:The new version of analog sensor port pin mapping has been changed as the following two features.Please check the tips for changing sensor cable pin mapping while using the I/O Expansion shield. We will continue to update. For the inconvenience caused, please understand.

WWH-10 DOF Mems IMU Sensor
Introduction
At the beginning,the inertial measurement unit is an electronic device that measures and reports on a craft's velocity, orientation, and gravitational forces, using a combination of accelerometers,gyroscopes, and magnetometers. Now IMUs are commonly used in the Human-computer interaction(HCI), navigational purposes and balancing technology used in the Segway Personal Transporter as we all known.
The 10 DOF(degrees of the freedom) sensor is a compact and low cost IMU from DFRobot. It integrates the ADXL345 accelerometer, the HMC5883L magnetometer,the ITG-3205 gyro and the BMP085 barometric pressure sensor. It's suitable for most of the controlling system because of the small dimension. The mounting holes make it possible to provide the highly accurate and stable sensor data.It embeds a low noise LDO regulator for supplying a wide range power input.Works with 3~8 volts power input.Certainly,the 10 DOF sensor is directly compatible with your Arduino boards.

WWH-1pc Fingerprint Scanner - 5V TTL (GT-511C3)
Fingerprint scanners are awesome. Why use a key when you have one right at the tip of your finger? Unfortunately, they're usually unreliable or difficult to implement. Well not anymore! We've found this great fingerprint module from ADH-Tech that communicates over TTL Serial so you can easily embed it into your next project.
The module itself does all of the heavy lifting behind reading and identifying the fingerprints with an on-board optical sensor and 32-bit CPU. All you need to do is send it simple commands. To get started, just register each fingerprint that you want to store by sending the corresponding command and pressing your finger against the reader three times. The fingerprint scanner can store different fingerprints and the database of prints can even be downloaded from the unit and distributed to other modules. As well as the fingerprint "template," the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor!
This is the updated version of the GT-511 which has an increased memory capacity. The module can store up to 200 different fingerprints (that's 10x more than the old version!) and is now capable of 360° recognition.
The module is small and easy to mount using two mounting tabs on the side of the sensor. The on-board JST-SH connector has four signals: Vcc, GND, Tx, Rx. A compatible JST-SH pigtail can be found in the related items below. Demo software for PC is available in the documents below, simply connect the module to your computer using an FTDI Breakout and start the software to read fingerprints!
Note: The module does not come with a cable, check below for an appropriate one.

WWH-Triple Axis Accelerometer MMA7361
Introduction
The MMA7361 from Freescale is a very nice sensor with easy analog interface. The MMA7361 is a 3.3V part and outputs an analog voltage for each of the three outputs. This voltage is in ratio to the measured acceleration and to the supply voltage (ratiometric). It has selectable sensitivity by dip switch. You will need some extra hardware to convert this analog signal to a usable digital one. The Arduino is really good option for it. This break board is especially designed for Arduino which has 3 JST connector that can be easily plug into our IO/Sensor expansion board.
Notice:The new version of analog sensor port pin mapping has been changed as the following two features.Please check the tips for changing sensor cable pin mapping while using the I/O Expansion shield. We will continue to update. For the inconvenience caused, please understand.

Features:
1. Adapts PPM decoder chip- Atmega32U2 to take charge of the surveillance and controlling of PWM signal of mode channel so as to switch between manual mode and other modes, thus improving the security of the whole system.
2. The directional data provided by the inertial measurement unit (two-axis gyro and single-axis gyro) and triaxial accelerometer (to measure the speed of three axes and accelerate the speed), cooperating with the three axis magnetometer or GPS can be corrected to realize directional cosine algorithm and calculate the attitude of aircraft.
3. Integrated with MPU6000 (three-axis gyroscope + triaxial accelerometer), MS5611 berometer and HMC5883L three axis electronic compass.
4. Supports data transmission to realize the remote receiving of real-time data from the aircraft
5. Supports pan-tilt control technique of professional cameras to ensure anti-vibration aerial photograph
6. Supports airspeedometer to measure the airspeed of aircraft.
7. Supports airspeedometer to ensure stable flight and low voltage protection of voltage detection in real time.
8. Integrated with 12-bite high-precision AD chip which can convert the analog voltage output by airspeedometer and the temperature output by three-axis gyroscope, triaxial accelerometer and dual-axis gyroscope into digital value.

WWH-GY-4988 A4988 3D Printer Driver stepper motor drive module
GY-4988 A4988 3D Printer Driver stepper motor drive module
A4988 is a complete microstepping motor driver with built-in translator for easy operation. The product is available in full, half , 1/4, 1 / 8 and 1 /16 step mode to operate bipolar stepper motors of an output drive capability of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator , the regulator can operate in slow or mixed decay modes. Converter is easy to implement key A4988 . Just enter a pulse in the "step" input drives the motor to produce micro-step . Without the need for phase sequence tables, high frequency control lines, or complex interfaces to program . A4988 interface is ideal for complex microprocessor is unavailable or overloaded applications.
In the micro-step operation, the chopper control A4988 automatically selects within the current decay mode ( slow or mixed ) . In mixed decay mode , the device is initially set to a fixed part of the rapid decay in downtime and slow decay for the remainder of downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry provides to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes : thermal shutdown with hysteresis , undervoltage lockout (UVLO) and crossover current protection . Special power sequencing.

WWH-1pc DHT22 Temperature and Humidity Sensor
DHT22 is a compound digital temperature and humidity sensor which outputs calibrated digital signals. Thanks to the dedicated digital module acquisition technology and temperature and humidity sensing technology applied to the module, DHT22 comes with very high reliability and excellent long-term stability.
DHT22 includes a capacitive moisture sensor and a NTC temperature measuring element which is connected to a high-performance 8-bit microcontroller, resulting an excellent quality, super fast response time, strong anti-interference ability and extremely cost-efficient.
Compared with SHT10 temperature and humiditiy sensor, DHT22 enjoys a higher precision and lower price, making it an ideal choice for mid price range, high performance temperature & humidity sensors.
If used together with Arduino expansion boards, you'll easily get interactives of correlation between temperature and humidity perception.
Note: DHT22 digital temperature and humidity sensor is designed for analog sensor interfaces. The analog interface is used as a digital one which will not occupy other digital interfaces on the Arduino. You can also use the analog-to-digital-converting cable to connect DHT22 to digital interfaces.
Humidity Response Rime: condition: 1/e(63%)25?, 1m/s in the air
