hello everyone,
I am the student of a university in Vietnam. I use MSP430 to read analog output of pulse sensor and write heartbeat on 7-seg. But the datasheet of this sensor haven't recipe convert from vol( analog output of sensor) to BPM ( heartbeat) ( vol/BPM). Example: LM35 sensor: 10mV= 1oC (V/oC). Please help me. tks so much.

 

Hello,

Did you read the documentation of the sensor in the links on the sensors page?

yes, i was. but i'm not good arduino. the recipe of arduino :A= (Vin/Vref)*1023. but this code haven't something like this.
EX code:
...
temp = ADC10MEM;
tempC = temp*423/1023 - 282;

 

Hey brother, i am student same you. I have project with sensor heartbeat,i don't really know how to read ADC of sensor heartbeat. You can help me?
