Hello,

I purchased recently a GT-511C3 fingerprint sensor. When the sensor is on I can feel the chips are getting warm. I would not say it burns my finger or I cannot hold my finger on the chip, but still it is relatively warm. I checked the datasheet and it says in the first chapter (1. Concept) "In the idle state, please turn off the whole fingerprint module. The sensor's metal frame can be integrated with a touch IC to wake up the module."

Does that mean this device cannot/should not be turned on all the time?

Do you have any experience running it for long time?

Regards,
Norbert
