Guest Posted February 21, 2005 Report Share Posted February 21, 2005 hi all,i had been given a task to complete a project. the project is a vehicle that have circuitry or sensor that can detect heartbeat and then display the heartbeat rate in the output. the problem is i couldn't find the model of the sensor that able to do that. for the alternative, i planned to amplify a mic so that it can detect heartbeat but once again i have not much knowledge about the amplifierr model, the number of gain i should choose and the circuitry to perform the task which include filtering. somebody help?? :-[ :'( Quote Link to comment Share on other sites More sharing options...
