Commands
[FINGER_PRINT]
Recognizes fingerprint and returns the registered ID.
| Item | Type | Description |
|---|---|---|
| Fingerprint ID | READ | Returns the ID of the registered fingerprint. ID 0 means no fingerprint detected, negative values indicate errors. |
| Wait Time | WRITE | Enter the time to wait for fingerprint recognition. If this time is exceeded, ID returns 0 (no fingerprint). |
[ENROLL]
Enrolls a new fingerprint. Fingerprint ID must be in the range of 1~127.
| Item | Type | Description |
|---|---|---|
| Fingerprint ID to Enroll | WRITE | Enter the ID of the fingerprint to be enrolled. (1~127) |
[VERIFY_PWD]
Verifies the sensor password.
| Item | Type | Description |
|---|---|---|
| Sensor Password | WRITE | Enter the sensor password. |
| Password Match | READ | Returns true if password matches, false otherwise. |
[SET_PWD]
Changes the sensor password.
| Item | Type | Description |
|---|---|---|
| New Password | WRITE | Enter the new password to set. |
[DELETE]
Deletes a registered fingerprint. Fingerprint ID must be in the range of 1~127.
| Item | Type | Description |
|---|---|---|
| Fingerprint ID to Delete | WRITE | Enter the ID of the fingerprint to delete. (1~127) |
[GET_PARAM]
Reads sensor information.
| Item | Type | Description |
|---|---|---|
| Status | READ | Status |
| System id | READ | System id |
| Capacity | READ | Capacity |
| Security level | READ | Security level |
| Device address | READ | Device address |
| Packet length | READ | Packet length |
| Baud rate | READ | Baud rate |
[GET_TEMPLATE_COUNT]
Reads the number of fingerprints registered in the sensor.
| Item | Type | Description |
|---|---|---|
| Registered Fingerprint Count | READ | Number of fingerprints registered in the sensor. |
[EMPTY_DATABASE]
Deletes all fingerprints registered in the sensor.
Example (AS608)
Objective
Register multiple fingerprints in the sensor and display the fingerprint ID on dashboard widgets when a fingerprint is recognized.
