Description
DIY Smart Door Lock BIO Fingerprint Relay Switch Biometric Fingerprint Identification Module With App for Attendance
1. This product is small in size and powerful in function! Record fingerprints directly on the fingerprint head, no third-party programs are required. The fingerprint data will not be lost when the power is turned off. The highlight is that the WeChat applet can also trigger the relay action through Bluetooth 15 meters away. It has a wide range of application scenarios, such as access control locks, computers, industrial control, electric vehicles and motorcycles, etc. 2. It can be powered by an external battery (4 AA batteries can be used), an external switch button can be connected, and the relay jog time can be adjusted in seconds! It can restore the factory settings by itself, and all function settings are completed on the control panel, which is fast and convenient. 3. The factory default is open mode, all fingerprints can be turned on, the first and second fingerprints recorded in succession are administrator fingerprints, after that, the control panel is locked, other fingerprints are pressed, the red light will be unavailable, and the management The operator presses the green light, and the relay outputs a signal at the same time.

Working principle
Press the fingerprint or press the switch icon in the mobile phone applet, the module outputs a relay signal (jog, self-locking, and ignition can be adjusted in three gears), this signal is the switch output by default, or you connect the common terminal to the positive power supply, the relay NO will output voltage to ground.
Working Mode Settings
Switching method of jog/self-locking/ignition mode: when the circuit board is powered on, press the "setting key" on the circuit board, the green light on the circuit board will light up, the blue light will flash, and the number of flashes will be from 1 to 2 to 3 have been cycled, and after pressing the button again, the mode is confirmed. The blue light flashes once to represent the relay jog output. The blue light flashes twice to represent the relay self-locking output. The blue light flashes 3 times to represent the relay ignition output (suitable for car and motorcycle ignition). Relay jog time setting method: The factory default jog time is 1 second, press the "set key" for 5 seconds and do not let go. The red indicator light is on, and the number of times the blue light flashes represents the corresponding relay output time. After the corresponding number of flashes, press the button to confirm the jog waiting time, 1 flash means timing 300ms; 2 times means timing 600ms; 3 times means 1 second; 4 times means 2 seconds; 5 times means 3 seconds; 6 times means 4 seconds; 7 times for 5 seconds; 8 times for 10 seconds; 9 times for 60 seconds; 10 times for 10 minutes;
Reset: First press and hold the "setting button" on the circuit board, then turn on the input power of the circuit board, the red light on the Bluetooth board is on, and the fingerprint white light is on at the same time, and the light is off to complete the factory reset.
Fingerprint entry steps
When recording fingerprints, please make sure that the fingerprints are clear and clean, and there is no broken skin! This fingerprint module has the ability of self-learning. Every time the fingerprint is verified, it is a perfection of the fingerprint information, so as to play a role in making the fingerprint more useful! 1. Entering the management fingerprint for the first time: When the system is in the factory state, press any finger on the fingerprint window for about 5 seconds without releasing it, the pink light will be on, remove the finger, and the pink light will flash quickly, indicating that the operation of adding management fingerprints is entered. Press your finger, press the finger continuously 3 times after the dark blue light is on, the green light is on for about 3 seconds, the new fingerprint is successfully registered (if the red light is on, the registration failed!) After the registration is successful, the pink light continues to flash quickly, and you can record continuously For multiple fingerprints, if you need to end the input, the program will automatically exit after about 10 seconds without any operation. Note: 2 or more management fingerprints must be entered for the first time, otherwise, the entry will be regarded as invalid! 2. Enter more management fingerprints: You must press the management fingerprint on the fingerprint head for about 5 seconds without releasing it, the pink light will turn on, remove your finger, the pink light will flash quickly, and enter the operation of adding management fingerprints. The entry process is the same as above. 3. Enter the fingerprints of ordinary members: You must press the management fingerprint on the fingerprint window for about 8 seconds and not release it, the pink light will turn on in turn, the light blue light will turn on and then remove your finger, the light blue light will flash quickly, and enter to add common members. Fingerprint operation. The entry process is the same as above. 4. Delete all fingerprints: You must press the management fingerprint on the fingerprint window for about 11 seconds without releasing it, the pink light will turn on in turn, the light blue light will turn on, remove your finger after the second pink light turns on, the pink light will flash slowly, Enter the delete all fingerprint operation. At this time, press it again with any finger, the green light will be on for about 3 seconds, and all fingerprints have been deleted successfully. At this time, the system is restored to the factory state (demo mode), and any fingerprint can be recognized. 5. Delete the fingerprints of ordinary members: You must press the management fingerprint on the fingerprint window for about 15 seconds without releasing it, the pink light will turn on, the light blue light will turn on, the pink light will turn on the second time, and the light blue light will turn on for the second time. Then remove your finger, the light blue light flashes slowly, and enter the operation of deleting the fingerprints of ordinary members. At this time, press it again with any finger, the green light will be on for about 3 seconds, all ordinary members' fingerprints have been deleted successfully, and the management fingerprints are still available. 6. Fingerprint verification: press the fingerprint for about 1 second, the green light will be on if the verification is passed; the red light will be on if the verification fails.
