I thought That sensor https://www.sparkfun.com/products/11651? will be work for my Final Project of college but it does not answer. Im trying find a solution, if I find them notice.
PROBLEM: "Well, I'm trying to get it to work communicationg with an arduino (ARDUINO MEGA 2560) serial port, which also uses TTL level, by sending the packet structure that the datasheet has, and I tried in both 9600 and 115200 baud rate (the datasheet says default is 9600, but sparkfun's video in youtube says is 115200). any idea how I could get it working, or what I might be doing wrong?"
I bought this cable https://www.sparkfun.com/products/10359 with the same seller of my sensor, I didnt know that I needed to buy it.
That's the datasheet http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/Biometric/GT-511C2-V1.5.pdf it's a chinese device so I dont have much information about it.
Anyone know anything more about this sensor or someone worked with this?
