PIC based anger detector

Probably you’ve noticed that anger rises a heart rite and blood pressure goes up. This is because anger generates high level of adrenaline and noradrenaline. So these factors can be measured and evaluate the level of persons anger. In this particular project is only a heart beat rate used as parameter. Wouldn’t say that it is accurate – heart beat may rise due various factors like sport, scare, etc. In other cases this works – you can try it on your friend by annoying him 🙂 project itself consist of analog part where LED-LDR based transducer is used to get heart beat – it is same way as in pulsoximetry. Op amps rises signal levels up to digital levels so PIC16F877 could read and then interpret data. Further information is sent to LCD where message indicates your anger level and suggests to stay calm. Continue reading
