Zigbee Smart Home Compatible Optical Fingerprint Module for Sensor

Description

Tutorial: How to Use Optical Fingerprint Module

This optical fingerprint module is ideal for Zigbee-based home security projects. Suitable for beginners and intermediates, it allows the implementation of fingerprint recognition features.

What you need

• Arduino UNO or compatible
• Zigbee Shield
• PC with Arduino IDE
• Optical Fingerprint Module ARD001052
• USB Cable
• Zigbee Libraries

Steps

1. 1. Install the required Zigbee libraries.
2. 2. Connect the optical module to the Arduino via the specified pins.
3. 3. Check the datasheet for power specifications.
4. 4. Configure the serial port on the PC.
5. 5. Load the example code onto the module.
6. 6. Insert a finger into the module’s slot.
7. 7. Verify communication with the software.
8. 8. Test the fingerprint recognition function.

Example code

```cpp
#include <Zigbee.h>

Zigbee zigbee;

void setup() {
  Serial.begin(9600);
  zigbee.begin();
}

void loop() {
  if (zigbee.available()) {
    Serial.println(zigbee.read());
  }
}
```
