About FPM10A Fingerprint Sensor

• Supply voltage: DC 3.6 ~ 6.0 V / 3.3 V
• Supply current: < 120 mA
• Peak current: < 140mA
• Fingerprint image time: < 1.0 seconds
• Storage capacity: max 130
• Safety level: Five (from low to high: 1, 2, 3, 4, 5)
• False accept rate (FAR): < 0.001% (security level 3)
• False reject rate (FRR): < 1.0% (security level 3)
• Search time: < 1.0 seconds (1:500, mean)
• PC interface: UART (TTL logic level) or USB2.0 / USB1.1
• Communication baud rate (UART): (9600 X N) bps where N = 1 ~ 12 (default value N = 6, ie 57600bps)

How to use ?

We provide a sample Arduino code, which can be used to test/learn the working of FPM10A. This code is tested on Arduino Uno

Installing Fingerprint library

To interface FPM10A with Arduino, we need to install fingerprint library

Configure with Arduino

FPM10A has 6 pins, in which we will be using 4 of them

• Ground
• Rx [To be connected to pin 3 of Arduino]
• Tx [To be connected to pin 2 of Arduino]
• Vcc [3.3v - 6v]

This is how we connect the FPM10A to Arduino for testing

Now we can upload the sample code to Arduino

Sample Code

In the sample code, we are using SoftwareSerial [Rx: 2; Tx: 3] so that the normal Serial pins Rx and Tx is free for debug

You can get sample code from our Github repository
