FAQ

Question:What signal does the WAKE pin output?

 Answer:

The WAKE pin is a wake-up pin, which only works when the RST pin is low and the module goes into sleep mode. The fingerprint metal shell outputs a high level after detecting the finger and returns to a low level when the finger is released.

Question:How to realize the wake-up function of the finger sensor?

 Answer:

After the finger presses the fingerprint module, the level of the WAKE pin will change. The MCU recognizes this level and sends relevant commands to control the fingerprint module.
