13 best fingerprint scanner for arduino

Product description

NOTE: Please use IDE 1.6.6



Features:

Make adding fingerprint detection and verification super simple.

Typically used in safes-there's a high powered DSP chip that does the image rendering, calculation, feature-finding and searching.

Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search.

You can also enroll new fingers directly - up to 162 finger prints can be stored in the onboard FLASH memory.

There's a red LED in the lens that lights up during a photo so you know it is working.



Specifications:

Supply voltage: DC 3.8-7.0V

Operating Current: <65mA

Peak current: <95mA

Fingerprint image time: <1.0 seconds

Window area: 14.5*19.4 mm

Signature File: 256 bytes

Template files: 512 bytes

Storage capacity: 1000



Attention: There are basically two requirements for using the optical fingerprint sensor.

First is you'll need to enroll fingerprints - that means assigning ID #'s to each print so you can query them later. Once you've enrolled all your prints, you can easily 'search' the sensor, asking it to identify which ID (if any) is currently being photographed.

You can enroll by using the windows software (easiest and neat because it shows you the photograph of the print) or with the sketch (good for when you don't have a windows machine handy or for on-the-road enrolling)

Product description

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 more economical version of the GT-511 which has a decreased memory capacity (compared to the GT-511C3). The module can only store up to 20 different fingerprints but is capable of 360° fingerprint recognition and download and upload templates using serial interface. If you are on a budget and need only a small number of fingerprints stored, this is the perfect option for you!

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 is included. 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!

Dimensions: 37 x 17 x 9.5 mm

Attachment cable included

PINOUT: from LEFT to RIGHT = TX (3.3V level - black wire), RX (3.3V level), GND, VCC (3.3V to 6V)

• High-Speed, High-Accuracy Fingerprint Identification using the SmackFinger 3.0 Algorithm
• Download Fingerprint Images from the Device
• Read and Write Fingerprint Templates and Databases
• Simple UART protocol (Default 9600 baud)
• Capable of 1:1 Verification and 1:N Identification, 360° Fingerprint Recognition

DHT11 Temperature and Humidity sensor

DHT11 digital temperature and humidity sensor is a composite sensor which contains a calibrated digital signal output of the temperature and humidity. The dedicated digital modules collection technology and the temperature and humidity sensing technology are applied to ensure that the product has high reliability and excellent long-term stability. The sensor includes a resistive sense of wet components and a NTC temperature measurement devices, and connects with a high-performance 8-bit microcontroller.

HC-SR501 PIR Motion Sensor

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. PIRs are basically made of a pyroelectric sensor, which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted.

GY-521 Triaxial acceleration triaxial gyroscope sensor

GY-521 six-axis sensor usually consists of two which are accelerometer and gyroscope. The GY-521 is a 6 DOF (Degrees of Freedom) or a six axis IMU sensor, which means that it gives six values as output. Three values from the accelerometer and three from the gyroscope. It is also a sensor based on MEMS (Micro Electro Mechanical Systems) technology. Both the accelerometer and the gyroscope is embedded inside a single chip. This chip uses I2C (Inter Integrated Circuit) protocol for communication.
