Capacitive Fingerprint Module Round Fingerprint Scanner Identification Module for Attendance Access Control


1. Capacitive Fingerprint Module: Can independently complete fingerprint collection, fingerprint registration, fingerprint comparison and fingerprint search functions, and has the advantages of small size, low power consumption, universal interface, high reliability, simple use, scalable large capacity 1: N identification, etc.
2. Self Learning Function: During fingerprint recognition, the newly extracted fingerprint feature value is successfully identified and fused to the fingerprint database, making the operation easy for users.
3. Automatic Correction Identification: 360 degree automatic correction and identification function, press the correct registered finger at any angle on the module, and the comparison can be passed.
4. Low False Acceptance Rate: A maximum of 0.0001% can be achieved, that is, one fingerprint from a million different fingerprints can be randomly selected, and other fingerprints from a million miles can be compared with the selected fingerprints in turn, which will result in a one time recognition pass.
5. Low False Rejection Rate: The maximum is 0.0001%. Among a million existing fingerprints, the fingerprints in a million fingerprints are compared for a million times in any order, and the recognition fails once.
6. Wide Applications: Can be used in fingerprint access control machine, fingerprint root finder, fingerprint attendance machine, fingerprint locker, fingerprint car one button startup, fingerprint lock, intelligent control equipment, etc.


Item Type: Capacitive Fingerprint Module
Material: PVC
CPU: 120mhz Main Frequency, 1M Bits Flash Memory, 128KB SRAM
Fingerprint Collector: Capacitor Collector 192x192 (pixels) 508dpi
Fingerprint Registration Capacity: The Default Value is 1000
False Acceptance Rate (FAR):<0.001% (security Level is 3)
False Rejection Rate(FRR):<0.1% (security Level is 3)
Comparison Method: (1: N) and (1:1)
Fingerprint Template Size: 570 Byte
Security Level Setting: Level 1 to Level 5 Can Be Set, Factory Setting Value: Level 3
Fingerprint Feature Extraction Time:<0.45 Seconds
(1: N) Comparison Time (when 1000 Pieces Are Fully Registered):<1 Second
Communication Interface: UART, 3.3V TTL Level
Serial Communication Parameters:
No Parity = none, 1 Stop Bit=1
No Flow Control=none
Baud Rate: 9600, 19200, 38400, 57600, 115200 (bps)
Factory Setting: 115200bps
Working Voltage: Win Voltage (DC3.3v ± 10%)
Working Current: Less Than 100ma
Interface Definition:
RST: Reset the Module, and the Low Level is Valid (this Pin is Needed when Supplying Power to the Module Uninterruptedly, and It is Recommended to Hanging in the Air in Other Cases)
VIN: Fingerprint Module Main Power Supply, Default 3.3v
GND: Power Ground
RX/DP: Module Receiving Data Pin
TX/DN: Module Sending Data Pin
+3.3v: Power Supply of Finger Detection Function Circuit
Wakeup: Finger Detection Function Output Pin, Which Outputs High Level when a Finger is Pressed
The specific operations are as follows:
1. The+3.3V of the module shall be kept powered all the time and cannot be disconnected.
2.Low power consumption is required. Disconnect the VIN power supply. At this time, a finger contacts the glass of the fingerprint collector. The WKP pin of the module will output a high level, and then turn back to a low level.
3.After detecting the high level of WKP output, when the fingerprint module needs to work, turn on the VIN power, wait for 350ms, and then send a command to the module.

Package List:

1 x Capacitive Fingerprint Module


1. In the communication process, except for the FP Cancel command, the sending and receiving of other commands must follow the principle of one sending and one receiving. The interval time between two commands is required to be greater than or equal to 20ms, and less than this time may lead to no response to subsequent commands.
2. When transmitting more than 24 bytes of data from the module target to the host, use the response data packet.
3. When the host does not receive a response, please do not send a command to TARGET.
4. The module indicator does not need to be controlled by default, and the collector indicator will be automatically turned on when processing instructions. If the correct fingerprint is collected, the indicator will be automatically turned off; If the correct fingerprint is not collected, the collector light is always on. You can also use the Sensor LED Control command to turn on or off the collector indicator according to your needs.
5. The device has password protection mode. After the device password is set, most commands cannot be used without password confirmation. If no device password is set, all commands can be used without password confirmation.
6. When the module is powered on, it will automatically enter the initialization, which takes about 300ms. It is recommended to wait for 350ms after powering on the module, and then send the command to the module.
7. This module has an automatic finger detection function, that is, in the low power consumption mode, a finger is pressed on the fingerprint collector, and the Wakeup pin of the module will output a high level.
